Your plan is good to start off with. See if that works for you first. However, what I would suggest is that you take/DRIVE...1 hour 30 minutes prior to your workout, then take AP a half hour after /DRIVE and wait your 15 mins before consuming your pre-workout meal...this way you avoid any absorption issues with RPM/DRIVE as it would mean you would have taken both 45 mins prior to any food. In my experience this is what has worked best and what I recommend to most people.
Now if your worried about the RPM/DRIVE effects not doing their job because of taking them so far out from your workout than you could always get ballsy and empty the powder out of the caps and take the powder straight a half hour before working out..., but it is not something I would recommend ....the powder is downright horrid to try to take down straight, but if you can tolerate it the effects are quite awesome in the gym!
You got to do what works for you bud. Everyone is different. Try your strategy for a few days and then maybe try my strategy and then see what works better for you. When you figure out which strategy works better stick with it. It really is a game of trial and error. Either way good luck and get back at me if I can be of any further assistance!
