For the ppl with the bow/DL questions, I'm pulling more like 54 or 55# at my 30ish" DL.  My arrows are 32" long, and I did originally shoot a 400 spine, but kept getting weak spine issues.  I switched to a 340 and got my arrows to fly just like my fieldtips. My 340 arrows are more stable and fly straighter, so I don't really care what is idealy the "correct" spine.

Agreed.  I shoot a similar setup and they bareshaft just fine plus have small gaps.  Experience is confirmed by 3-rivers calculator showing a near perfect match at around mid-50s in dynamic spine.  Any arrow 32" long & loaded up front is going to be very bendy compared to a 28" or 29" arrow.

I can't speak to the terminal damage of the heads you mention but I've shot a few.  Zwickeys are good but I'd stick to the double bevels -- even on the No Mercy heads.  The extra layer of metal on the tip is fused over the side blades, creating an odd transition that is nearly impossible for me to get a good, smooth flat edge on the unbeveled side.  You could opt to make the sides single bevel past the transition and keep the tip as a double bevel.  But why complicate things?  

I got frustrated with trying to regrind angles on my grizzly heads so I put those aside for this season & picked up some Zwickey Deltas.  I could have just used the No Mercy heads I already have but I figured if I couldn't have a single bevel, I'd at least have a wider cutting diameter.  Like any Zwickey, they sharpen with a file or whatever I have on me (pocket knife sharpener, car window, etc.).  Plus they're cheap, easy to find & solid enough for anything I'm chasing.  If I can get the grizzly angles set better, I may take them with me for my late season hunt.  But I just didn't want to mess with them anymore this close to the season opener.

All shoot well if you do your part.
