the difference betw. the bx2 and the f4's is simply variation.. the bx2 is most beans probly like 75% of all females will be very close if not identical to swerves sfv clone..picked up a pack of these bx2's and not only the gems are in the females,but the males are really what are special, being able to pass these genes onto bigtime females.., its gonna be amazing..theres about a 40 to 1 chance that you will get a pheno better than the sfv og..,
w/ the f4's theres alot more recessive genes going on in there, prob get more variation but the chance of finding real sfv ogk pheno is very good also, prob will yield better IMHO and finish a bit faster than the sfv ogkbx2.. both are going to be bomb.. sick work swerve!!!
