Ha haI could see it being extremely difficult to roll with a bag.

I guess just lazy vaults and stuff like that would be ok - you just don't want to be caught off guard and catch your foot on something and fall on your face


Also, every time you change your pack/move some stuff around in it, the weight of everything will be different and you'll have to acclimatize all over again.. Although then again I've never tried it intensively, so it could work
