Not tooo long ago, my MS stick died, and I purchased an evo as a quick fix until I could find another MS on ebay.
One thing I did that helped me out tremendously was the spring at the base of the stick, where it meets the base, I created some "shims" for it. I would push the spring up, and slide in a shim. I messed with diff. types of shims, starting with cardboard, and diff. thinckness to create more tension. By putting in the shims, I increased the "resistance" of the stick, and found it much easier to controll. Got the idea from someone here on the BBS.
