Well, after all this time I finally got around to going to three springs and refloating it. It wasn't that hard actually. I found that the handle of one of my screwdrivers made a perfect block for the trem. With three springs it seems to have plenty of resistance, which I like. I also like being able to palm mute without the bridge moving. I'll test it some more but I think it's a keeper this way. Then I'll have to decide if I want to put two new holes in the trem cavity for my trem stop.
