Since I'll probably go with the old dependable wet cell batteries I realize my high demand loads will have to be kept short.

As others have said, voltage sag with 4 wet-cell GC2s might be a problem at high starting loads. You might have better luck with 4 AGMs, ...
WOW !!! That is a pretty "broad brush" statement !
From my "non-expert" knowledge, there is NOTHING in an AGM battery design that makes is battery at handling high starting loads.
A quick, simple, but crude way of comparing battery A to battery B (assuming they are both deep discharge batteries)[/] is simply look at the weight. More weight means more lead means it is capable of storing more power.
all depends on the application it was designed for
there are AGMs engineered for high current
i know of one that is rated for 500watts per cell for 15 minutes until cell voltage drops to 1.65v
thats over 400amps
thats (6) cells aka 3000 watts (400+amps) for 15 minutes from (1) 12v battery
can't say what that will do to battery life or recovery
but YES, AGM can be engineered to produce very high amps
