Thanks
@LOBALOT. Here's my two cents ...
IMO, it's well worth trying PP Black Out in this situation. The caveats ...
1/ Frequent Restringing required (no probs if stringing labour costs are token or nil)
2/ PP BO 1.24mm seems to work best in a full bed between 50 to 54lbs.
Restringing frequency is likely to be similar to RPM Blast. VC (esp 16g) will probably give an extra 2 or so hours of optimum playability compared to PPBO and RPM.
For an elite junior player I don't expect more than 3 to 4 hours of optimum play from PPBO. (Probably 4 to 6 Sets of Singles Play) IME, this compares with RPM. VC probably 8 to 10 Sets.
So crunch the numbers. If a player has several racquets (ie. 4 or more), and restringing labour costs are low or nil, it's worth a demo.
Saying all that ... IME, Volkl Cyclone Anthracite is still one of the best and most versatile value for money CoPoly strings available.
