I am dead serious. This mod made my Iron Maiden play WAY better.
I have IM right next to IMDN to judge how they both play based on weight. I would say 35-40 pounds is what the game is short in weight. I have 25 in there (15 in the middle that I put in the bubble bag & five on each side), and it still wobbles a bit, but it is night and day for feel!
I just used spare weights from our weight room, but I'm going to eventually get four 10 pound dumbells and put two on the centre sides and two at the back, which will be perfect for where Stern removed weight.
Maybe I should start a business. "PinWeights" anyone?
