Played some singles against a solid 4.0 the other day and he was using the X1. he has 3 of them and they all looked brand new, even though they are all over 10 years old. he could not say enough good things about it. I tried one briefly in the mid 2000's and I liked it but It a tad stiff for me back then. Anyone still using these?
