I know the SS is thicker than the aluminum, but is the series 2 aluminum thicker than the series 1 aluminum? I've been having issues with the stainless. I guess it's the weight or how it presses into my nerve on my arm (and I don't wear it tight), so I'm thinking I'm gonna have to go back to aluminum. The thing is, I don't want to go to a series 2 aluminum if it has more thickness than the 1 (which I had before I bought the series 2 SS). I'm pretty darn disappointed about this, but I don't know what else to do. I've tried different bands, tried to make it hit different spots on my wrist, etc., and it is NOT helping.
