I have fished Otisco once. Weeds on trolling gear is a problem on that lake. I know from Justin's posts, he catches a lot of fish approx. 28' down or so. It would seem to me torpedo divers may be the easiest way to get you to that depth. Yes, Amherst is perfectly located.....1/2 hour to Lake Erie, 20 minutes to the Niagara, 35 minutes from Lake Ontario, 1hr 20 minutes from Canandaigua, 1 hr and 45 minutes from Lake Chautauqua........so many options.....so little time.
