Those packs are ideal. If you mount the landing gear just behind the motor, it is easier to get the GG right with lighter packs. It also helps prevent nose overs so it's a good prop/shaft saver too. I had an 80 gram Nimh pack that worked ok, but the wings were clearly stressed. I wouldn't dare a loop as even a light gust of wind would bow the wings too much for comfort.
With a 2s 720 it would really float and loops were safe. I used bamboo skewers instead of CF though, so you can likely get away with more weight.
