I agree with the above, try both methods. But don't completely give up on your two-step until you have it setup properly. The only way to do it right, according to a lot smarter people than me, is to run a brake pressure sensor instead of a button, and to use a brake pressure gauge. This way you can stage at the exact same pressure every time. You can add or subtract pressure to increase or decrease your reaction time. If you get an adjustable pressure sensor as well, than you are really good to go and have a lot of options.

But still... even with all that.... I'm just as consistent with the footbrake. It depends on what works for you.
