Two big blokes looking for a dinghy

I think I know what he's saying.  (5420 could you just read through what you've written before you post it - we don't expect imaculate spelling but your's is hard to read.)

400s like all those other big roached mainsail boats do respond to tension down the leech.  So if you make sure the kicker goes slack when the mainsheet is hard in you'll find that you can modulate the power with the last couple of inches of mainsheet, this will enable you to smooth out (to and extent) the variations in wind strength.  Probaly 5420 realises this when he's in his 29er but didn't in the 400, or maybe 5420 wasn't on the helm?
