Asymmetrical Chute Gear for Cat

[sailvi767]

I have ordered a asymmetrical chute for a 45 foot cat. It will be a 1.5 ounce chute about 1200 sq ft. It will be bridal rigged. I wondered if anyone has advice on how to rig a bridal and what system of blocks they use to give the most adjustment including being able to move the tack point to the windward hull. I also wondered what size sheets most would use and what strength turning blocks I will require to lead the sheets to the spinn. winches. I am planning 3/8 inch sheets at the moment but same are saying 1/4 inch will work. I know lighter is better within reason. An recommendation on a specific turning block that is reliable and available at a decent price would also be appreciated.

Thanks!
