I have had both types and the old sails as good as the new.
I cut the stop off the part on the cross bar on the 14 type and with a loose rig d-mast at the Outer Banks race after I turned over in very big wind. If you are going to cut the stop out take the metal off the mast base. This will keep the mast from kicking out when the boat is over with a loose rig. Got the new type when I went to fix the problem. Don't think it will come out unless your on your side.When you step it just lay the chain plate on the tramp keeping the wiers in front of the ball and pick it up when you get the mast up.
Good Luck!!
