I don't cool, I pair year round, I do an heavier than usual feeding schedule for the females every 5 days when they start becoming voracious, I never pair more than 2 days at the time making sure each males get around their designated females once or twice a month (depend if the male is experienced or not) and I like my males to be around 650 grams and up.
No two people do things alike what matter is to find what works for you and your animal.
