Big differnce is by time ribs are sawn to get at the tenders its as fast to have the animal internals completly gone not to mention flipping one over is easier. For me its a toss up niether take me anywhere close to 2 hours to accomplish either way..
I used to cut ribs to get to the loins, but after awhile I just started to reach in with a small knife and could cut them out. It's tricky if you don't know what you're doing, but practice makes it easier.
I got tired of dealing with the gut sack. Even if gutless wasn't faster i'd probably still do it.
Try to put your tree stand in a tree with plenty of background cover, keep the prevailing winds for that time of the year to your face, and take care of those pesky squeaks and creaks your stand may have developed while sitting in the shed. A good treestand lube can be made by heating petroleum jelly until it reaches a liquid form. Some hunters have reported success by including a cover scent in this mixture before applying it to their stands.
