Indeed, RF is insanely stable however, I've always added a bit of bumper tapes around the hoop.
At 12, 8 and 4 o'clock area for my liking. The tape do not add a lot of weight (it will eventually...) but, it definitely makes difference, (I don't like to use lead so, I add a lot of bumper tapes instead, depending on racquets).
For H22s, these do not require to be weighted up to like RF97ish... (I've removed weights from the RF and it became unstable so, I've added weights back on lol...)
Bumper tapes at 12, 3 and 9 (covering 4 cross strings.. like pws...), added leather grip and two overgrips, one with overlaps and one without...
Also added x3 5 pence coins at the butt cap which comes up to 347.52g. It is not my final spec but, it seems like it will be... trust me H22 feel much stable at the current weight. It won't get pushed around by other heavy racquet users,,, aka RF97 users.. ;-)
Power and stability is more or less the same, if not more from H22. Maneuverability, more or less the same..
