The bertram change also looks amazing! way outta my league right now, but I'm eager as hell and I practise about 2-3 hours a day. on top of that I work 40 hours a week, produce music and have a two year old daughter. the day just ain't long enough!
Hum, mine would have to the Twirl change, the 'so simple yet most underrated' double lift change (in spectator hands, of course) and the 'Color Change' taught by Ricky Jay.
