i really really enjoyed watching that. consider the web page favourited until a downloadable version comes along edit:your riding style rather reminded me of adam bessels, just the way you are very upright and well i dont know lol. either way its not a bad thing
my bb7 203 is a beast on the front, but there is no way that i would trust on the back end of the bike. it holds wonderfully for front wheel moves but i just dont think it would be so succesful on the rear. i dont really like the feel of rear discs either to be honest, even on a mod where they are supposedly good.
the bb rise isnt that high on them so its probably worth keeping the lower stem although some people like the feel of low bb, high stem; ie bessel and nicky g
