im a baseliner who uses heavy spin especially on forehand. lately i have been getting shoulder soreness when i string full alu rough or even hybrid mains with alu rough and volkl cyclone in crosses. im looking to use a softer/less harsh poly for my whole stringbed that generates alot of spin. i have narrowed the decision down to 3 polys. 1) TF black code 2) volkl cyclone 3) signum pro tornado. Are they all pretty much the same? Which is the most powerful. Any feedback would be appreaciated.
