I am yet to see ah2 on my feeble CPU, but in ah1 the P47s were at their best when at hi alts (over20k), then of course there is that long winged hi-alt perk ride, the name escapes me at this time.
My personal favorite thing to do with monkeys is to up a 262, the long range and extreme speed can allow you to come in behind the monkeys as they travel to their target. Often they feel very comfortable at 20-25k so they dont check6 as often, The 262 can intercept well under these conditions. My fave tactic was to achieve excess E, then dive in on them, cut engine before hearing range, coast in behind them nice and close, quick burst then start engine and search for next victim.
NOTHING can compare to the feeling of sending some alt monkey back to tower when they just reached cruising alt
