I know b all about trialling but I would guess more weight on the drive axle is more grip between tyre and 'road'.
Seems to me you want the minimum possible drive torque that will get you up - once your wheels are spinning it doesn't seem to get better. Thus revving in first may not be the best.
Mere speculation - would be delighted if someone who knows what they are talking about would correct me!
