What lip do any of the builders use for Donnies?

Med Donnies all 4 styles used Lefty # 2's high slot for 2 under water swimmers and slope the surface used a low slot
The larger Donnies used Lefty #2's also but the surface swimmer used a low slot #3 pikie lip and the large slope used a #3 pikie high slot.
