Anyone breeding for size?

Is anyone doing any selective breeding to try to increase size? While ASF's are great from a size standpoint, I'd like to produce larger ASF's for those larger female ball pythons.

When holding back for breeding I made sure to hold back the larger ASF's I had to try to get larger offspring. I have a few males that are almost 150 grams that I will be breeding. I'll be making sure to hold back noticeably larger offspring to breed and try to get larger and larger ASF's.

:O Holy crap! My boy is only at 100 LOL, You have some monsters over there. I'd love to see how big you can get them.
