Cobra Speedzone Vs Cobra Radspeed Irons Comparison And Review

Pitting Cobra Vs. Cobra. What were we thinking? This was one of our hardest comparison overviews to do because both of these irons were designed by the same people to do the same thing: increase ball speeds.

However, we pushed through and were able to pluck out a few key differences between these two irons. Right off the bat, we did not test the single-length Radspeed irons even though that is an option.

Cobra Speedzone Irons Overview

The Cobra Speedzone irons are predicated on ball speed and forgiveness. Indeed, these are one one of the most forgiving Cobra iron sets we’ve every played.

The Speedzone irons definitely have a satisfying feel even when you miss the sweet spot. That is most likely due to the forged face insert that effectively expands the sweet spot.

Yes, you read that right. You get a forged face insert in a game-improvement iron with the Cobra Speedzone’s.

The insert also features a deep undercut to improve flex at impact. The distance of these irons has always impressed us.

Initially, they were yielding around 15 yards of extra distance in the long irons. Really, our only gripe with them is that they lack a bit of short game control.

Cobra Radspeed Irons Overview

The Cobra Radspeed irons are also predicated on increasing ball speed but they go about it in a different way…

Instead of increasing flex and forgiveness around the face, Cobra decided to tweak with the weight of the Radspeed irons.

The Radspeed irons feature radial weighting which is essentially just pronounced perimeter weighting.

The slightly forward-oriented weighting system of the Radspeed’s lowers spin rates. In general, the lower the spin rate of the ball, the longer it will carry.

Indeed, the Radspeed’s were yielding impressive carry distances with a low shot trajectory.

They produced a low piercing speed as opposed to the higher-arcing, powerful speed of the Cobra Speedzone irons.

This also made them a bit hard to work around the green. On the other hand, the 3D printed rear medallion gave the Radspeed irons the superior feel.

As we predicted, this was a tough one to call. In the end it will come down to your preferences as a player.

If you like more lift and arc from your irons, go with the Cobra Speedzone irons.

If you are looking for less spin and a flatter trajectory, pick up the Cobra Radspeed irons.

Cobra Radspeed – First Impressions

The first thing to notice about the irons is that they have the chunky sole of a game improvement iron and the strong lofts are made for ball speed and distance

The 10g screw weight in the toe of the club also jumps out to use and it is complemented by a matching weight in the heel of the club for the perfect CG and a high MOI,

As soon as you start striking these irons, you notice the power and consistency in the clubs, when you catch a hold of the large grips and start letting some shots rip.

That is for good reason, they are crafted with AI for perfect weight placement and the 3D printed medallion on the back improves stability and reduces vibrations.

The thin flexible face offers a ton of forgiveness and ball speed and these irons also have plenty of turf interaction for the better players.

Cobra Speedzone First Impressions


When you first pick these irons up, it feels like that are too light to deliver the kind of distance that beginners with slower swing speeds need.

However, after you play around with them, you’ll realize that they do in fact produce good ball speed – even if you have a slower swing speed. The deep undercut allows the face to flex to a high degree; unleashing fast ball speed even fore beginner players.

We tested these irons in graphite shafts but you can also get them with KBS Tour 90 steel shafts. The graphite irons added to the distance and overall feel of these irons. They helped keep the weight down and contributed to flex.

There are also rear badges on these irons that are made form a combination of aluminum, acrylic foam and thermoplastic polyurethane. So even on full-bore swings, these irons maintain a nice, smooth feel.

The Cobra Speedzone irons don’t look or feel like much at first; but they really shine in terms of distance and forgiveness.

Who are the Cobra Speedzone Irons for


The Cobra Speedzone irons would definitely be more suited to high handicap players.

Don’t get the wrong idea of these irons; they will not offer a lot of value to low handicap players. They don’t have the dynamic spin control that low handicappers value. They also don’t offer very much in the way of shot shaping ability.

However, none of that really matters if you are a high handicapper who is really just starting to get the hang of your irons. The price is right too. You can get a brand new complete set of Cobra Speedzone irons for around $600.

The Cobra Speedzone irons are definitely for high handicappers who need help in the distance and accuracy departments. While they won’t be able to help much as you lower your score; the relatively low price still makes them a decent value for high handicappers and beginners.

The Radspeed Irons from Cobra

Cobra also makes the Radspeed line of irons that are geared more toward mid to low handicappers.

If you are looking for better performance around the pin then the Radspeed irons would be better for you. They even come in single length sets if you want better consistency. The Radspeed irons are a more complete set as they are designed to play long while the shorter irons enhance spin control.
