Hello, if you have wide "old school" FH loop, then R50 is quite nice for FH, if you have more modern "compact" "tensor orientated" FH loop, then R50 might be not your cup of tea... It's just R50 play great, powerful and with a lot of control when you fully adored it's hard sponge, but when you try to play soft loop it's control is bad and if incoming ball have a backspin it can just fall down from your racket, the reason is Rasanter topsheet not have much spin, so spin is mostly created with a sponge, the pros of it is that it's not very sencetive to incoming spin, so it's great for flat shots... For now I changed R50 and tenergy 05 on my Apolonia blade to XIOM Omega 7 Asia, might try it om Mizutani as well, but don't know if it's help me to make Mizutani my main blade, at least with Tenergy 05 and/or Rasanter R50 Mizutani ZLC is too fast for me to handle at close to the table distance...
