If your budget isn't too much, I'd pick up some Bioval 0.30g AND MadBull 0.40g and try both out and see how you like them. You're right, the environmental factors and the way your gun shoots might give you a different experience than others.
I've used MadBull 0.40g and while they are certainly far from the best, they did well in my high FPS set-up and I was pleased with the results.
