I know some people who go lighter than 1500 although personally I shoot between 1500-1800, and I tend to lean more torwards 1800.

If you do decide to breed her this year, i'd personally run your het albino male through her. It seems your best chance to get albinos, then if you have a male albino you can sell your het as proven and use your male albino to breed to get better shots and proving out poss-het females, and if you get a female albino, you could use her to prove out poss-het males and worst case you still end up with 100% hets.
