Damn, two hours usually? That's about the point where I start to get antsy and want to get out of the gym. How long are your rest periods on most days? 5 mins?
I debated saying this, but IMO you don't really need a spotter on bench. I never ask for one unless its a 1RM, because anything else I can handle if I fail. Are you pretty good at rolling the bar off of you? Might be a good technique to try. I have to do it every once in a while and it's much better than asking for a spotter who wants to do partial deads with you while you're benching haha.
