I agree, too complicated. On my 30 footer I have the crew pull in by hand with two wraps when it should be almost all the way then they add a wrap one handed and then the winch handle goes in. At this point it should be only the last bit of fine trim as the boat comes up to speed.
If you are finding the tack is complete and you still have a lot of sheet to pull in under pressure than likely your helmsman is tacking too quickly. It is better to tack slightly slower and get the jib in than it is to try and winch it on on your new course.
