Hey, Ive been a big synthetic gut fan for a few years now. Ive tried PSGD, LightningXX, Wilson Stamina, and some others. PSGD is my favorite of all. Im currently upping my game and going for an RDS001 MP. Part of me is saying to move up on the quality/composition of strings as well. Im not a frequent string breaker, so durability is not too much of an issue for me. Ive done alot of searching around this forum, and noticed that many ppl like the Tour Super 850's for their Yonex's. That's what I'm currently leaning towards, and I was wondering what(if any) the power difference between a synthetic gut(PSGD) and a multifiliment(850) is. Any opinions/input would be great. Thanks.
