Another thing to mention is that this uses a pull spring instead of a compression spring so the resistance is the same the entire stroke. I just got a 5000 DW and I was seriously disappointed in the fact that they use a compression spring. I think I'm gonna stick with my Pearl untill I can get my hands on a lathe and make some parts to convert this DW. It's also gonna get a lever glide linkage like this TAMA but the fulcrum will come from the bottom via chain. Should be fun.
