I am pairing both of my female spiders to my butter male this upcoming season..... Butter isnt a cheap ingredient there isnt really a cheap 2 gene butter animal most butterbees are going to be 750-1000 on a male and probably more closely toward the higher end of that range. Working on nuclear stuff, pic up a butter female for 3-400 bucks and then save up for a firefly male.... Wont get you nuclear spiders, but firefly males are so strong and versitile.
