aerobatics rich or leaned back?

[pigpenracing]

Well I am finally comfortable in my IO-540 Skybolt I bought in December. I am going to start doing some acro on every flight from now on. It took me a bit to get everything adjusted correct so I can wear a parachute. When you guys fly acro do you leave it full rich or should I lean it back some? I have a fuel flow meter and it shows about 23 GHP at full power. I guess I will fly acro at a 25/25 power prop setting. Didnt know if I should pull it back to 18 GPH or so or just pour the fuel to it? What is better?
Thanks, Shawn
