Of course it's possible to do all those things really well in hards, (and I'm sure you do)... remember Damian Sanders? All I'm talking about is what works for ME in my everyday riding, be that teaching, racing (softs and hards), riding pow, steeps, bumps, running courses/clinics etc.
For the record, when asked I don't count myself as either a hard or soft booter but as a snowboarder.
