Hey!! lots of choices out there... Ive been most impressed with Dinafem's Critical+ . ive grown a nice NL x BB from Nirvana in the past, but thats discontinued. I hear female seeds ww x BB is really good if thats the one u had. A new one thats out that looks like its gonna be a big hit is Barney's Farm Critical Kush. also theres a breeder who sells the Kritical Bilbo strain, which is a special phenotype of Critical+ ... do watch out for lame BB crosses tho... some have really low THC which is unexcusable considering the new stuff on the market that is really bomb!!
