When you breed two snakes the male should only be in the same enclosure with the female for a few days at a time, so it's fine to use whatever size the female is usually housed in. 28/32 for smaller females and 41 for the big girls. If you need more space take out the hide so they have more room to get closer together. After 2-3 days put the male back in his enclosure and give him the rest of the week off so he can relax before you try again. It may not look like a lot of work, but I've heard it's possible to breed males to death.
