It seems the Mack Pack has the most consistent approval. I’ve reached out to them and will hopefully get one setup soon. It seems folks feel the one negative is that there aren’t any battens, which causes the pack to not as cleanly catch the main, necessitating a bit more cleanup after dropping. Doesn’t seem a deal breaker to me though - the system seems tidy, and I like that it can be rolled down to the boom and the lazy jacks retracted to the mast.
