Okay so ever since my Grapplesnake string testing a couple months ago I've been trying a bunch of stuff all over the board like yonex poly tour spin, luxilon 4G, tier one black knight & firewire, mayami magic twist, polytour strike etc. All really good offerings, finally came back to my racquet tonight thats still strung with Tour Sniper and was absolutely loving it.
Its so hyper accurate compared to vast majority of strings I've used really unusual... ALU Power is the only similar string, I'd say that or polytour strike is the 2nd most accurate. Sniper is the perfect name for this string cause the crazy precision stands out more than anything else. It must be seriously low powered cause its easily taming my most powerful racquet an oversize 105 Prince Legacy O3. Primary difference between ALU Power & Tour Sniper is in feel & depth/power I believe... ALU Power seems to be far more powerful and tends to hit very deep. Tour Sniper has a nice very controlled low power response, I noticed I can easily hit very short topspin forehands with it inside service box or at service line... and then I can easily swing out more to hit extremely deep shots if I want. I actually prefer the way ALU Power feels at contact but im not sure it gives too much advantage in gameplay, and Tour Sniper feels less harsh. Very consistent response to reliably hit the way you want to constantly.
I see why one of your sponsored female pros said she uses Tour Sniper because her style is based on low unforced errors. Its perfect for that with the high precision, very consistent response, low power, and high control. Even compared to its most similar string ALU Power it still offers quite a different experience and playstyle.
I agree that mostly Grapplesnake is just lacking recognition and awareness and can compete with the top string companies in quality of product & price. Similar to Prince in having very innovative top notch products like premier control, premier touch, vortex, and Tour XC. I've seen nothing but very positive reviews on almost all your strings on here and on stringforum.
