Personally, I wouldn't recomend either for first, unless you are already an acomplished 3Der. Not that you can't fly'em but you get a lot more time to think and easier recoveries with the thicker straighter wing planforms, ie Knife and Burrito. I got my first Taco too soon and it was a waste.

After LOTS of time with Knife, SPA3D, and Burrito, FF Taco is now my fav of all. But you gotta be on it ALL the time. My Sledge is still getting dressed, but even if it's easy to fly, I wouldn't want to learn on it. Burrito Builds easier and stronger, better for all my dorks!
