Assuming you have a boat Dom, Ill stick to the south pond, I have more experience there than the north or middle. That said, there is a super drop off from about 15 to 40 feet as I recall on the eastern side of the middle pond that is AWESOME.
South pond, I always liked the big point that comes off the west central area of the southern end - about half way from the massive point that almost splits the south pond to the big swampy area in the SW corner. That swampy area was also good... and fun to fish as well. There is a large rocky hump between those two spots that is good all the way round.
Tip of the big lake splitting point is good, it's like a long saddle that makes it almost to the narrows and has sections of coontail edging up to rock.
The SE corner of the south pond is soft bottomed and has some great lillypad fishing. Here's a map of the contours from mdfw: https://www.mass.gov/files/documents/2016/08/tm/dfwwebst.pdf
