What mast are you using for your 10.0 m2 sail.
A higher carbon/lighter weight mast might help also.
The Easy- Uphaul is not a "tool".
It's simply an uphaul "system" with another loop part way up the
uphaul line that allows you to hook the uphaul on your harness and
simply leam back to bring your big sail out of the water.
Lot's of semi pro racers who use big sails also use the Easy Uphaul.
Hope this helps,
