I also use a pro stock blade 98 but in the 2015 glossy paint job. I believe under the PJ is the 2013 wilson blade. It's a definite solid performer because it has a natural sw of 335 strung.
I'll try out the v7 blade if anyone I know brings it out to the court.
Remove the leather grip, go back to to the regular syn. grip and inject silicone in the handle.
I found this somewhere on the forum.
1 - Get a reel of cheap synthetic gut.
2 - String the frame at 75lbs
3 - Cut string out,
4 - Repeat steps 1-3 until reel is finished.
