hahah i don't think it is anywhere flexible. it's very stiff for me. it's probably up there with zf2. ZF2 was so much easier for me. here's a picture (provided by our fellow member ucantseeme)
I am considering buying a z-speed and have a couple of questions that I hope someone knowledgeable can help answer: #1: What version did Carolina Marin play with? I know Tago and some other mens single players prefer the 2U version. #2: What about doubles and mix players who previously used it, what version did they play with? #3: Does the SP distributed play any different than the JP marked, or does anyone experienced paint/finishing differences between the two of them? Any advise on what to choose? Someone tried both of them? Thanks!
