Mark, I used the two part sheets on an 18 ft race boat and loved the precision of the sheet adjustment. For every 2 inches you trim on the sheet the sail lead only moves an inch.

I just ordered some new Harken #450 jib lead cars. I'm using them in combination with Harken 40mm Carbo blocks with becket and cams#2646. I'm going to attach two Carbo blocks to the clew of the jib so I can run a continuous two purchase jib sheet. I saw this set up on a local one design racing boat "505 open" a boat of french design now being manufactured here in Southern Cal. This two purchase set up eliminates the need for winches on jibs 140sq ft or smaller. Now all I have to do is order the longer track. But I can still run this set up on my short OEM tracks in the mean time. Man I love sailboat hardware !! :) the rigging possibilities are staggering.
