PFT is your standard basic synthetic. I personally think that in a hybrid as a cross, most solid core synthetics have a similar enough feel that paying say $7-8+ for a single set of SCsynthetic to use for ONLY cross strings does not justify the cost for me. I rarely string poly/SCsynthetic for myself anymore but if I do I just use one of the softer cheaper solid core synthetics.
I was thinking along the line of using a reel of PFT for testing, I was also looking to see if there are other strings that may give more spin and pop than PFT. I do like the performance of PFT.
You could get more pop by dropping the tension but you will probably get some drop in control. You could get more pop with a multi or gut but you usually give up some spin. You could get more spin with a thinner gauge or with poly strings. I'm not really sure on how tension affects spin. Then there is also hybrids...:?
There are just too many strings out there that we would need more information to make recommendations so how about starting with these ?s. 1)Do you have a price range for sets or reels? 2)What is your play level and how many hours does it take you to break PFT and NXT? 3)What other setups(string and tension) have you used, likes/dislikes?
Also, how much do you like PFT compared to NXT?
