heya and welcome i agree that corns are definitely more handleable and slightly easier to keep as you don't have to worry too much about humidity. if you get a royal undoubtably you'll join the 'arrggh, my royal's not feeding' club at some point wheareas corns are more like dustbins
Then get a Royal. Just be aware that Royals aren't as easy as corns, so you might have to put a bit more effort into keeping him happy. Great snakes though
