I can share what I have done in the past. I did purchase foil bridel extenders and only use slightly more mast rake then with the chute. Rick Bliss sells them, they get the pole up higher.

Most of the NE 6.0s have the spin blocks off the rear beam, with another set of blocks near the jib track.

I switched to a halyard block arrangement similar to the I20 set up and that works well allowing the mast to rotate. I currently use seperate lines for halyard and tack.

I have never had a problem with the halyard tangling, the biggest area of trouble I have found is running over the chute. We raise the haylard, then pull the tack for luanching the chute. For take downs, it is the oposite, retreive the tack and then lower the chute. This methode prevents the chute from getting run over.

A sailor from Maine built a beautifull custom midpole snuffer for his 6.0 and that is really the best way to go.

Good luck.
