@TennisManiac and anyone else curious - At least for the PA23, I found the one-hander very doable, even sometimes preferential, such as when having to hit a flat or topspin BH on the stretch, where I actually felt the extra lateral stiffness and torsional rigidity made the difference between being able to solidly punch back a ball with enough depth and pace, versus not. In those instances, had I a flexier, narrower-beamed stick in my hand, I might have been able to finesse the head angle/location and/or locate to the shot a bit more precisely, but probably wouldn't have been able to hit as heavy or deep of a counterpunch, or do so as consistently time and time again.
There's something about the above characteristics of the PA23, which gives it a high amount of what I "cradling" (for lack of a better term) -- an ability to preserve the intended face angle, all the way through and beyond contact, with almost complete resistance to twist, flutter or being knocked off-angle or off-path. And it goes beyond just a simple high twist weight, or basing it off plow-through/swing-weight alone. I think it's also from the beam shape -- the triangular throat pieces blending into the fully elliptical hoop -- and crisp/direct layup. It produces a lower half of the racquet that is extremely twist
and flex resistant, in
any direction, coupled with a hoop that is extremely flex resistant perpendicular to the string bed. Overall, this results in an otherworldly level of stability, one that belies the fairly pedestrian static weight and swing weight. It's a highly tuned instrument in stock form, that's for sure.
All of that said, as much as the PA is really a perfect 2-hander's frame (because all of that stability and twist resistance is really best overcome and utilized with 2 hands on the handle and 2 arms at work), for a certain amount of one-handers with a strong-enough, clean-enough motion, it can be just as fantastic, maybe even more so. As that implies, though, you
must have a certain level of strength and pronation range, as well as a powerful-enough core twist -- think: Justine Henin -- in order to benefit from the qualities I outlined above as a one-hander. But if that's you, then I think the PA23 could offer
a lot for a OHBH. If that's not as much you, ie. for those whose technique is more wristy or they arm or bunt their way through most of the stroke, I can certainly see how it could be challenging, to say the least.
I hope at least some of that helped!
