Yes, F100s were awesome! I have a 2 stager w/ F100-0 booster and E5-6 sustainer that rocked! Unfortunately, the last time I flew it, I used a modern composite-type ignitor (rather than the old FSI ignitor), and lit the top of the core. There was a "BANG-whooooooooooooooooooooosh" as the F semi-cato'd and lit the sustainer! The rocket recovered normally, but the rear of it was toasted.
As stated earlier, BP motors are easier to stage, and that big honkin' nozzle of the F100 was sooooo cool to look at!
