Bridget,
As I alluded to in one of the above posts, I've been hunting down the right combo of good feel, good solid stability, and a little bit of extra juice. To wit I've been testing frames for a while, and tbh I'm very keen to settle on one as it hasn't done my game any favours. Of all the frames I checked out my faves were the very different AG 100 and the Exo Reb 95 (heavy one not the team.) At present I'm pretty close to committing to the Rebel, but I just want to see how I fare against better, big hitting opposition (which I shall do tomorrow.) I've posted quite a lot on both my tests as well as the Rebel, so do look them up if you think they might be of interest.
RE the Babs, because of a long association with their frames, I'll always have an interest in them I think. I must also confess to having a hit last week with my old PD (non-Cortex, standard model.) One of my slight issues with the Reb is it is a little slow on reaction shots or for those last-second wrist-flicks, etc, so I again felt a need to reinvestigate. However, the PD, for all its qualities, just feels to flimsy. And moving on, the PDR always felt odd re its balance and it plays very stiff. And my old faithful PD+ just feels too long and big (for a long time I've wanted to come down in head-size) and I felt too jammed up with it. And as for the PST, whilst it had control and touch far superior to any Bab I'd hitherto tried, I was never actually sold on the feel, and I always missed that bullying power one associates with the PD, PC, APD, etc, etc.
Good luck with your 'quest' though Bridget!
