neither?
I've owned both, and have been dissapointed by both. Neither system performs well in a breeze. As liveaboards, we use our grills two or three times per week year 'round, often enough to burn them out every couple of years, and I keep going back and forth. I've recently switched from the cylinder-type Force 10 to the new flying-saucer-type Force 10, with which I'm having limited success. The reason I have been favoring the Force 10's these past few years is that they use less fuel. 95% of the time we fire up the grill it's just for the two of us, and since wonderblond doesn't eat all that much, the smaller Force 10's make a lot of sense. We hook ours up to a 2.5 gal. tank, and only have to refill it three or four times per year.
