Progressive Shocks

I went from the stock shocks to the 12" Progressives...these are the standard version and I find they ride quite hard...I weigh 195# all geared up and have tried several settings on the shocks..I wonder if I made a mistake in going with the lower 12" shocks and should have stuck with 12.5" or maybe up to 13" Progressives...I have added the front Progressive springs and they made a big difference too...I love the way the back end now stays planted but the hard is rock hard...Any suggestions?
 
Does anyone make fork springs with a lower spring rate than stock?
