Mike, you have obvious put your time in and learned the ins and outs of Montauk. Here is the problem, most of those famous Montauk blitzes were on smaller bait, whitebait, peanuts or other small stuff. Like you mentioned, you could catch a 30# bass the guy next to you could catch a 8# bass, the guy next to him could catch a 2# bluefish and the guy next to him could catch a random albie (on a bomber with a wire leader....... that was Sudsy 15 years ago). The point is, it was difficult to target larger fish, especially with a fly rod. I have been in a few big fish blitzes out there, but they are hard to predict so unless you're a local or happen to get lucky, your mug aint going up on wall at Paulie's .
For ten years there were epic bunker blitzes in NJ, I mean EPIC. The reason these this blitzes were special was because A) the large bass were more plentiful, B) they were eating 2# bunker. So the smaller fish in these blitzes were like 20#, some days they averaged 25# other days they averaged 35#. I could on and on with stories of the carnage, but I wont, all you have to do is look up historic NJ bait shop or fishing club tournament weigh ins from 2002-2010 and the see the dozens of 30# and 40# fish weighed in on a daily basis.
From the beach, the NJ bite and Montauk bite is no more, The Canal may be a decent bite, but it aint Jersey 12 years ago.
To the original poster, if you dont want to do the CBBT, Philly is probably 1 hour away from the upper Chesapeake and the Susque flats, that may be the best shot at a 50 on the fly, it's just not legal. So you're using a 10wt to catch shad and the flies you're using happen to mimic those shad, but arent they cannibalistic?
Find the big bait and you will at least avoid the smaller fish.
