I bought the Levy 4.5 a couple of months ago and it's a fine strap but, like someone else said, it is prone to digging into the neck. Your neck, not the bass neck. Haha. I'm hioing that it will soften up but there is a lot of padding on the edges and it doesn't seem to be going anywhere. I've used the 3.5's for years. Less padding or so worn out, Im not sure. I think I prefer them. And putting strap locks on the 4.5 hasn't happened yet. Way too thick. Fortunately, the holes fit so tight on the Dunlop posts that its not an issue. I dont like the neoprene or heavily padded straps as they stretch or padding wears out and bass changes position. I'm of the Billy Sheehan school of lock that thing into one place for as close to forever as you can get. I dont like folding my straps either andbthe 4.5 Levy is a beast to put away. I keep meaning to put my 3.5 back on and see if it's heaven.
