I have a martin prowler SE with first generation TRU -ARC cams. The modules I have say L-HL which go from 29 to 31.I need the lower modules which go from 27 to 29 S-HL .Do i have to change the cams and modules to go to the lower draw lenght,or just the modules.I found a guy who has some, but says the cams he has dont say small or large on them ,just the module.So i dont know if he has large cams and the small module.Any help will be Thankful.Thanks KEN
