What about a good set of BMX pedals and real grippy shoes like Five Tens? I've been told the soles of these shoes are SO grippy they really grab onto the pins of the pedals and won't bounce off. I am considering a pair of these shoes for myself.

I am considering the same remote control seat-post - but not this year. Once I have the basic skills under my belt and my trail riding to fall ratio reverses then I will do this. Because of my fit needs other than inseam, the saddle height on my Jamis is going to be well above my bars and I think that will make things easier later on to be able to get the seat post out of the way easily when I need to do so.

I couldn't justify it at this stage, even if I had the money...
