That is my only complaint about my Sterling, switching out springs for my velocity. On Saturday 11-10-12 I went out to my local field and played, just before I went out there I picked up a Spyder spring kit and what I did was cut the Black spring down to my Valve spring length put that in, I then used the reminder in the hammer. I have a Palmers Female Stabilizer set to 600 psi and I'm shooting around 280 fps (with properly matched paint to barrel). As for the "shims", #8 washers fits well into the hammer.
I hope that helps.
Enjoy your new toy!
