After talking to a few folks I think I'm going to stick with VPC - its not that much more than StaSet X.
Looks like I have to go with 10mm (which is a bit larger than actual 3/8) unless I want to switch out clutch parts. Hopefully the extra size is not a problem.
The site says main halyard length is 102' - anyone know if this includes the line to get back to cockpit?
