Hey guys I'm new and I got some questions. I know for my Iron Eagle I need to change the modules in order to change the draw length. How do I find out what type of module to buy? I went to Kames which is a shop by me the sells and adjusts bows and stuff and they said they don't sell modules for bows that old. I have found some online but IDK what model I need they say like H7 or E8 and stuff like that. How do I figure out wether I need an H or an E or whatever else they have? and also any advice you're willing to give to a noob would be greatly appreciated. Thanks guys
