I guess my question is how big is your budget that you want to waste recording time setting up not just one but TWO hi-hat mics. If you have a three month lockout, then I could understand spending the time on it, but if you are paying hourly, make it sound right as quickly as you can, and then get to making music. I have tried just about ever method of recording drums you can imagine, and I have ended up using hi-hat mics in the mix maybe a dozen times, if that many. Feel free to try it if you can justify the time, but understand that it will take time to get the positioning right so that you are not having phase issues which are too serious. Too be honest, I do not find hi-hat mics to be very useful.
Of course, my ideal setup for micing drums is a Neumann M50 just above and just in front of the drummers head, facing straight down. I may or may not add a kick mic (a Beta 52 most often, though RE-20s and M-88s are also great for some types of music) and one or two room mics, which will invariably be SD omnis, hopefully B&K (now DPA) 4006s. Squash the room mics like Momma Cass' throw pillow, and you have the best rock drum sound you will ever hear, I promise.
Of course, this all assumes your drummer can play.
