I personally love hybrids. Burm x ball, blood x ball, carpet x ball, retic x burm, retic x ball, carpet x condro. I think they are all awesome. I wouldn't mind dappling in some myself, but producing any of the hybrids takes years. Sometimes you'll get a lock, but won't produce eggs. Or you'll produce eggs that are slugs, or only a couple of hatchlings.

Burmballs, bateaters and blood x ball are my favorite hybrid.
