I am converting my Supercat-20 jib to a self-tacking system and I am interested in the pros and cons of a curved track verses a straight track. I see the smaller cats all seem to have curved tracks and the larger cats have straight tracks like the ARC-27 & 30. Are there benifits to using one system over the other? Are both systems rigged the same way? I lauch a huge spinnaker off the tramp and I was thinking that the straight track would be less likely to snag the spinnaker upon retreival yet the curved track seems to me to be the better system as far as jib control goes. Any help or advice is welcomed.

Thanks, Don Caldwell
