I would definitely look into that new LRP / Reedy brushless system. Looks to be more powerful than the novak, can run brushed or brushless motors, and is smaller. If you want to do brushless but still have the option of brushed, can't go wrong there.
For a mod motor, I am really liking the trinity cobalt series. The V2 tech motors work well and have long time between rebuilds but just have to watch that they don't gum up in certain conditions.
