Well good luck with your searching. I would guess that if you are looking for exoplanets you should invest in a very good clock for your observatory so that the telescope tracks very accurately. Perhaps an exposure time is limited to how well everything tracks over say 1, 5, 10mins etc. but I don't know.
 
Most of the surveys mentioned have exposures of 2 or 3 minutes, but their main purpose is to cover as much sky as possible but still maintain quality.
