I've been playing with the Head Radical Pro, strung with gut mains and RPM crosses, and modded with **** pallets and buttcap. I ultimately play really well with this racquet and enjoy everything about it. Nice soft feel, solid hit, tons of access to pace and spin, nice feel at net. My only thing I have been having a hard time with is dialing in my first serve with this racquet. When I really go for it hard, it tends to sail slightly long. Not getting enough snap to bring it into the box. Luckily my second serve is such a weapon with this racquet that it has not posed much of a problem in match play, but I miss the ability to step up to the line and crank it with consistency. Coming off an APGT, and with a lot of other raquets like the EXO tour, Pure Drive Roddick, etc... I don't have this problem. Anybody have any suggestions for technique adjustment or set-up (like adding a little lead at the tip, or maybe going full poly) ? Is it the flex of the racquet that I love everywhere else, but throws off my first serve? I don't know. Maybe I just have to get used to it a bit more.
