Caz, unfortunately for most people it is just a case of suck it up until your hands develop the necessary calluses. YOur smaller hands probably would allow some extra movement to occur due the shaft being to wide for you. Long term I'd look at trading up to something more comfortable, Werner do offer a small shaft diameter for just this situation. What you could try in the interim is to apply a small amount of board wax to the point you hold your shaft ,might cut down on some of the excess slippin that can occur. Also if I remember correctly you have new type rough stuff blades with a blue shaft, it looks like the finish on some of those was quite rough, this might help smooth out some of the inconsistencies. The best thing of all about it is that if it doesn't work you can just rinse it off with hot water.
