It isn't a bad idea to keep an eye on you snakes weight especially if it is on a hunger strike. It is simple and quick. I don't think it is overcomplicating anything. It helps me to know what weight to feed because my eyes are bigger than her stomach by the time I select the live feeder at the shop. I find it easier to know I am getting the right size. Use what works. Est for you. After all it is only $15-20 there are worse things to spend money on.
