Not that I'm even close to an "expert" opinion (or even "half-a$$") here, but I have noticed that trying to hoist the spin from the wire works better with the beam mounted cleat/spinlock (on a swivel) better than a mast mounted cleat.

But I see the trend is for the driver to stay on the wire while the crew faceplants/hoists the spin from the front beam on the trampoline...

Is there a reason (now that most people run all the control lines to the crew's trap hook) the crew couldn't stay out and hoist (and adjust downhaul, rotator, and possibly hoist the windward board)? Probably wouldn't even have to come off-wire to grab the spin sheet, either...

It seemed a bit easier the few times in light/moderate (single trap) air when I did try it..we left the boards down for that day, anyway...
