Don't want to diss the system or anything because I've got it on my boat and I am pleased with it, however all the thing about mast compression and tacking, etc. How much does this affect your average Joe? I reckon that the dirrerence in mast rotation is probably slight when compared to the rest of the variables that affect mast rotation such as coke bottle top in base rather than teflon disc, rig tension, etc. I don't think I would personally go out and buy the system if my existing boat did not have it as I don't think I would suddenly be climing the leaderboard of the next regatta with one.
