Catnap, like you said it will be more than enough power. If you only have two loops and no incandescent lights one booster will be fine. You can also break a layout into districts by adding circuit breakers off of one booster. In other words you could put a circuit breaker for each of your loops with power coming from the same booster. This way if there is a short or derailment on one loop the other loop will not shut down. Just a suggestion.
