I bought the 444's with HD springs and I feel they are over sprung for me. I'm 200lbs and the wife is 125lbs. With just me on the bike, its definitely too stiff in the rear. With the wife on, it's better but still on the stiff side. I did get the standard springs from progressive, just have to swap them out but it's been way too hot for motivation level. The problem I had with HD springs was that I could not get the right mount of sag with just me on the bike. I had the preload backed off all the way and I was getting just under a 1/2 inch of sag when it should be an inch.
