I'm considering going with a MackPack or StackPack on the main AND mizzen of my 32' Evasion ketch with original sails (late 70's). It looks like I can do both sails with either one of these options for less than $1300-1400, Any comments on satisfaction or relative merits? I'd prefer to keep with my original sails, and I understand one is self installed while the other is installed by the provider. I think I can do the self-innstallation. Any experience and advice you can provide would be helpful!
