My physical limitations demand that I know what my game is lol. I'm not that tall (5'7") but I love living up at the net, even though I get lobbed a lot. And I'm about to cross over from mid 30s to late 30s. So my game style is basically approach on every short ball or approach on every deep shot that pushes the opponent back. Ideally I can hit heavy shots that force errors or short balls. I feel like the VC95 hits fast but not heavy, if that makes sense, whereas I feel like my 93P, VCP 97D, RF97, etc. hit heavy.
I like to warm up with my PS85, which is what I used for most of my playing life, and the reissue from TWE is about the same swingweight as the VC95 2021. When I volley with the PS85 I can do almost whatever my mind wants it to -- punch it deep, use touch, etc., and I've lately tried out the PSVS too which gives me the same -- but the VC95 has been such an exercise in frustration for me. I can only punch it and it has a tendency to fly even with poly at higher tension. Mostly it just feels like there's not enough weight to absorb the pace. I like the EZ98 on punch volleys but find touch a bit tough on that one too. FWIW, not saying the VC95 sucks at volleys, it just doesn't naturally fit the way I execute those shots and I'm sure plenty of better players make it work just fine.
Re stability, I only feel the lack of weight when I volley back a shot that is hit hard at me or when I play older dudes who tend to hit heavy and low through the court. That's where I feel the racquet get pushed back. But I don't know that I would call that instability, which I associate with flutter or torque. It's just that you can feel it losing the battle of momentum vs momentum unless you are really ready and prepped to kill the ball.
I have a 1 hander and that's one of the reasons I've tried sticking with it. It's fun how many different trajectories and angles you can hit and how easy it is to make those microadjustments. I actually really love my 1 hander so far with the EZ98, but I don't think I'm as picky as some when it comes to my 1hbh racquets. For example, I think the GPro is fine on the 1 hander, and I know a lot of people would disagree. Maybe it's because my first serious racquet was an oversize. That said, I do feel like my 1hander gets a bit more one-dimensional with a GPro (generally more flat) or the EZ98 (pace through the court vs. angles).
You make me curious about the Regna. If only it were easier to find! I did just get some VCore Tour 89s that I am VERY excited about. Sadly they will have to wait until my back feels better, as I may have reinjured an old herniation this morning during a lesson.
