Can some one make it a little more simple...
OK, I've read through all of the posts and I'm confused as ever...
What is the end effect if I ADD more shims to the ULT? Lighter trigger pull?
When is the end effect if I REMOVE shims in the ULT? Heavier trigger pull?
I've been racking my brain all morning playing with mine. I finally got the Level-10 tuned properly and now moving to ULT.
Answering my own question :-)

My solution was to file the bottom of the pin down enough to make it work with 4 shims. Since adding shims = a shortned pin anyway, I figured i might as well just physically shorten it.
If you try it, I would suguest being VERY careful. Also, make sure you grind the BOTTOM of the pin. That would be the end that sticks out of your vavle and contacts the sear.
So far so good. I installed a LVL10 as well. I have to wait for a break in the weather for me to put some paint through it, but it sounds pretty good.
Im going through all of this trouble so I can install a spyder frame on the gun.
