elwilliams13 Posted March 3, 2008 Report Posted March 3, 2008 (edited) Start with a 280 main and work up or down from there doing plug chops.Leave your other settings the same as they are now. FMF suggests a 260 main on their site. If you don't know what the chop is then do a search and you will get more info than you will ever need. Edited March 3, 2008 by elwilliams13 Quote
