I have 1/4 inch shrouds. I've been tuning them to a J24 tuning guide times 3. The heavy setting is off the scale and extrapolated. I'm not sure it's really 3000 and I don't have the guide in front of me. I looked some Up and it might be 2600 that I shoot for. At the other end in light air I have been putting about 1000 on the uppers and 750 lowers.
I like to sail to boat like a J24 too. No twist, vang sheeting, I drive and manage the main as well (I've always thought of the main as an extension of the rudder anyway)...
