Trey had a problem with the exit block chafing the line. It finally snapped under the card sound bridge. The new pole end cap that david lennard made solves this.

I've never had any problems on our poles with the lines twisting. You have to use a swivel block on the inside. I'll diagram it.

I like the 2:1 for tack line for distance races so I can have a choice between blowing halyard or tack line for spin reaching.
