i don't want to discourage you, but you're not going to be happy downsizing. you might be satisfied for a while but you can't have near the inhabitants in the 30 as you do in the 75. more than likely you're going to just want to reset back up the 75 in a few months. once you have the itch there's no getting rid of it. the best solution would to be to just set both of them up, just kidding. don't make any hasty decisions.
