i had a long lay off in summer 05.
got injured in mid july and was off til october, with lots of phisio though.
at mid november i was already catching up, but the most difficult thing has been regain confidence in doing precarious moves or dynos, or anything really hard for me anyway.
in january i was very ok.
i think what helped me alot has been doing some light wheights, in order to make 4 sets of 25 reps for each muscular group. you lose fat, and you enhance the quality of the muscle, without gaining wheight.
and, moreover, you rip on da beach.
