Snell Golf was founded by Dean Snell and as I found out when I interviewed him, he has a background in creating top selling premium balls for Titleist and TaylorMade.
Now working for his own company, Snell has created a premium tour calibre ball called, maybe unsurprisingly, My Tour Ball which aims to give the same level of performance but at a cheaper price as Snell Golf sell direct and don't have the costs of big sponsorships to cover.
In the golf ball world there is a minefield of patents and Snell has 40 to his own name, so it is quite impressive that he has been able to get a 3-piece ball out at all in this category.
The key to the whole thing is the cast urethane cover as that is what creates the feel and control, but it is also expensive and hard to use so that is why you only find it on premium tour balls like the Titleist Pro V1 and TaylorMade TP5.
The urethane cover is soft, durable and thin in order to give the control that you would expect from a tour ball. Around the green and on approaches is where you would notice this and the My Tour Ball was up there with the contenders already mentioned in this respect.
In terms of softness it is probably similar to a TP5x in that it feels softer than a Pro V1x, but firmer than a Pro V1 on putts and most chips. For some reason on mid-range pitches of 30-80 yards it seemed like you could feel a firmer core, but that could be me and some may like that.
Using GC2, you can see how the spin helps generate more distance at a 100mph driver swing speed when it is compared to the Snell Get Sum ball, which is a softer 2-piece construction.
The firmer construction has a higher ball speed off the face as this speed and the extra spin gives it a 1 yard higher peak height from the same launch angle and therefore an extra few yards, but really it is the control around the green that separates the two balls.
Compared to the Pro V1x, the MTB was launching and peaking about the same with a driver for me, but with about 100rpm less spin it was carrying a couple of extra yards, which backs up the softness comparison I made earlier. As the Pro V1x is a firmer ball it will probably spin less, so as long as the launch is the same it may go further, so the decision here is on spin and feel.
With a 7-iron the difference in spin with the MTB is more noticeable as it spun much more than the Get Sum, but it stopped quicker as the higher level of spin worked with the lower flight for more control on landing.
Compared to the Pro V1x, the MTB also span about 500 rpm more for me, but the carry distance, launch, ball speed and every other number was almost identical so there is very little between them with irons.
However to reiterate, with premium balls it is about control on and around the greens and at about 30% cheaper than the market leader, the Snell MTB gives you similar levels of performance without a similar hit on your wallet.
