I've never used the Tru Glo but I have used the Impact Archery Cosmic which is pretty similar to the sight your looking at, and as for hunting ,it's all the sight you need .Most hunting situation's don't call for any more than a 30yrd shot ,and if you have it set properly all you'll have to do is drop the pin where you want and shoot .Anything further you may need to compensate a bit ,but a single pin is all you really need for hunting .
