Some unsolicited advice re pruning tridents whether you want it or not, Sean.
Much better long term result by chopping at an angle. I know it initially seems better to retain a side branch but the chop always looks odd. Most maples will usually sprout some new buds around the base of the remaining leader after an angle chop anyway so you'll still have the branch, just in a better position.

Same on the clump in post #205. I see you have angle cuts on a couple of the trunks in that photo (blue circles)
