given those two choices, I would run sidewinder for longevity, blue thunder for power.
I am sponsored by O'Donnell, so I would tell you to give it a try. If I wasn't sponsored I would still tell you to use it anyway. Anybody that knows Steve O'Donnell knows that he doesn't just put something out there unless he thinks its better. It took him two years to release his glow plugs. He could have just copied someone elses and had them out much earlier, but why do that. It's not his style. If you have access to O'Donnell fuel and glow plugs, give it a try.
