two stage setup

Just wondering what opinions there are for the setup I'm going to put in when I finally get a day off again. One ten# bottle, line running foward to a T-fitting and splitting off into two solenoids for a 2 stage dry setup. Single window switch set at 2700 and 5800 rpms, single WOT switch, and separate arming switches for each solenoid. 75shot for each nozzle. I have everything at home already, just wanted to hear some opinions and constructive criticism before I put it in.
