Buy the Traxxax lipos and put your mind to rest. It sounds like you are stressin about cutting the vents. I am all thumbs mechaniclly (see I cant even spell it) and it took me about 10 minutes on the first ones and by the time I got to the last Summit I could do it blindfolded. It really is no big deal. Besides its a better way to run your leads than coming out the side of the compartment in the little notch.
