Only problem is every gun even the same model can be slightly different. 400-500 users have it easier as if you're prepared to pay his price TR Robb sells a set a different hammer springs for them that you can experiment with. I managed to get set cheap off here a while ago which helped a lot but I did make some lighter, longer stroke hammers and different thickness spring preload spacers as well to mix and match until I got the optimum set-up. You could do worse than by checking Rob Lane's regulator YouTube videos there's one for every circumstance/problem. Not specific to the 200 but the principles are the same for every make of reg.
