Thanks for the information guys. Yes the PS 125 is a 18x22.
I usually string poly at a low tension ie: 50lbs in my 95-97 Dunlop CX 200 and Wilson PS 97s and have gone done to 45lb in a Dunlop Black Max which is about a 87-90 sq in. I recently started playing with polys more and more since I been getting better and love the control I get. So I went on TW store and got the 10 pack of yellow prince tour xc for $25 cause I tried them on a prince phantom 100 I demoed and they are a pretty dead/stiff string but I haven’t measure the length for each pack, I’m sure they were cut from a reel since they're in clear packs. I do love stringing a full bed, one piece. But will probably do a 2 piece in my racquets if need per suggestion, I do have a starting clamp for bridging but only done it once since I starting stringing 3 months ago. Luckily there was about 5in so tie off wasn’t harsh. the demo I play was strung at 50lbs and it was perfect but then again the Phantom 100 is a comfortable racquet. Again thank you guys for all the input, this really hleps
All the Best,
Jo
