I just converted my Attak to 151"x2" with 8 tooth drivers. I have a flatlander clutch setup, but I need some help with my Wyoming setup. I have pressed out all the rivets and changed primary springs with good luck previously. However, I have a set of Heavy Hitters I would like to setup for 9-10,000 ft so I just have to put the HH's in and not press the rivets. Can anyone give me a HH setup/spring combo that works? I only get 8 days of Wyoming a year so I don't want to do any testing once I get out there. Any help is appreciated.
