Jamie,

Think twice before wrapping any running rigging around your hand. It is universally a bad idea on any sailboat. The reason is if a sudden gust of wind comes up and the sheet begins to move it will take your hand and anything attached to it, with it. If your hand is near a block it will not feel good. And no, you cannot get your hand unwoud fast enough all the time.

That is the reason why we use the cam cleats. So we don't have to jam our finders into the block to hold the line.
