OK, I was a biology major the first time around in college. Your question is "would an F2 be good smoke?" Most likely the answer would be yes. To make it simple- 1/4 will resemble the parents (P1 & P2) of the F1, 1/2 will be like the F1 and 1/4 will be lesser quality. It's worth the effort. You have 3 chances out of 4 of getting good bud. It's really a lot more complicated since several genes are involved, but since the genes are mostly good ones, you have a good chance for some "killer bud".
