I machined my own and I just made them 3 degrees. If you're going to do a lot of driving in 4WD, I would get the 2 degree wedges. If you do mostly street driving, then go with the 4 degrees. The reason I would only use a 2 degree wedge in 4WD is to try and reduce too much front u-joint angle.
The info I'm giving you is what has worked for me with my setup, and it made a huge difference in feel and drivabilty. I don't get that side to side wander anymore that these Blazers are famous for.
I'm also running 33" tires with a 2" lift, so our setups are similar. When I put the wedges in I also added a factory front anti-sway bar, so I believe it was a combination of the two that made all the difference.
