Have to say what a good thread this is.
As a fixed wing pilot who then got a PPL(H) 3 years ago, I can fully appreciate where smtp is coming from.
I fly a lot fixed wing, but unfortunately, this year have hardly been near an R22, (much to my own annoyance). During the previous years, I always took one out at least once or twice per week, and focused on things like hovering, spot turns, landings, etc.. as well as simply flying around. In my opinion, rotary flying is much more of a perishable skill than fixed wing flying is, and it needs to be practiced on a regular basis.
A lot of good advice has been given to smtp on this thread, and I must say, I think it's also spurred me on to re-initiate myself with the R22, (albeit through an instructor in the first instance).
smtp - you are at this moment, current; if, on reading the good advice on this thread you do decide to continue with your flying, my advice is to make sure that you retain that currency. It's so easy to let it slip, (and your confidence with it).
Happy flying
