Taylormade Sim Max Vs Cobra Speedzone Irons Review & Specs 2021

Who couldn’t use a little more forgiveness from their irons? A lot of players go out seeking just that.

They hunt for a set of irons that are incredibly easy to pick up and play. The only problem is that they often overlook precision and distance.

The fact is that you shouldn’t avoid the challenge of mastering your irons. Forgiveness, scoring and distance should all be factors when you are shopping for an iron set.

And in today’s comparative review, we will be looking at 2 sets that promise those very things.


An Intro to Both Sets

 Taylormade Sim Max

The Sim Max irons came out it in 2020.

They were the apparent successors to the popular M5 and M6 irons and in terms of size, they are just between the M6 and the M5.

But the sole of the Sim Max irons has been refined for better turf interaction.


Cobra Speedzone Irons

The Cobra Speedzone irons represent the company’s ongoing foray into the realm of game improvement irons.

With the F9’s in 2021, Cobra began tentatively establishing itself in the premium iron market.

With the Speedzone’s they are seeking to build upon that breakthrough.


Key Features

With the Sim Max irons, players get the benefit of a stabler face architecture with superior vibration dampening.

The Speed Bridge connects the top line and the sole to afford more flex without a harsh feel.

Cobra has followed suit with more prominent club manufacturers who are all jumping on the bandwagon of discretionary weight.

The top line of the Speedzone’s is made of carbon fiber so that stark weight can be placed in the toe and heel for higher MOI.


Who Will Benefit?

Both of these iron sets are made for mid to high handicappers looking to take the next step in their game.

They both offer that sweet spot between maximum forgiveness and performance that make great game improvement irons, well, great.


The Sim Max Iron Family

The Sim Max iron family also includes the Sim Max OS irons.

The Sim Max OS irons have slightly lower lofts and there is more lacking in terms of vibration dampening.

Other than those two key differences however, the Sim Max and Sim Max OS irons have the same construction features.


The Speedzone Family


The Speedzone irons are available in standard and one length.

The one length versions feature all the same features like a carbon fiber top line and the Pwrshell face insert; but all the irons are 7 iron length (37.50 inches). This provides more swing consistency.

Composition Comparison

The Cobra Speedzone irons feature what Cobra calls their PWRSHELL face insert which goes behind the face, adding weight and stability to expand the sweet spot.

The molded medallion on the back is made from acrylic foam and aluminum. They feature carbon top line and steel head design and are available in steel and graphite shafts.

The Sim Max irons feature Taylormade’s inverted cone technology which expands the sweet spot out towards the toe. These irons feature a thinner face to produce more flex.

The heads are mostly stainless steel and they are also available with graphite and steel shafts.


Performance Comparison

As far as feel goes, the Cobra Speedzone irons performed better.

The acrylic foam medallion on the back served to dampen harsh low frequency vibrations. And the aluminum frame still keeps these irons light weight.

But the Sim Max irons provided more length and short game precision overall.

They certainly felt harsher but the thin face design provided more flex and ball speed. The Speed Bridge also made for better feedback in the shorter irons.


Price Comparison

There’s about a $100 difference between these two iron sets.

The Speedzone’s are generally pricier at around $800 while the Sim Max irons typically go for $700.

Final Say

Remember our criteria for this comparison were forgiveness, scoring and distance. The Taylormade Sim Max irons offered more on all fronts.

They were more accurate near the green, were generating longer repeatable shots and the inverted cone provided more accuracy on off-center shots.

The Cobra Speedzone irons felt at least twice as good as the Sim Max’s but fell a bit short in performance. The Taylormade Sim Max irons are our choice so check them out today!
