I'm not fully fluent with current 'T' trends but I have just set up my F14 and I chose the kis principle (keep it simple) so my halyard pulls the tackline. For me as a single hander I think it's a 'no brainer'? (did I use that term correctly)?
I see as much spare line on the tramp with either system but I have a shockord/bungey loaded block under the tramp which takes care of most of the slack. Had I positioned the rear eyelet a little further forward it might have removed all the spare line. <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />
I take the point that it would be nice to have the option of setting tackline tension from the trap.
Steve, you'll need two halyards if you want to change back to your original system as the newer one will need to be shorter, right?
