I couldn't find anything in black and white about this so I'm going to ask. If you want Velo 3 pads with Velo 2 graphics, the mods you would make are:
-Widen Leg Channel
-High Density Outside (vertical) rolls
-Add thigh flap
Those are the ones that I am 99% sure on. Is the thigh on the Velo 2 squared up? If not, that could be added to the list.
