I currently own 2 Palmers and performance wise they are both very fast, stable and quite accurate. They are probably the fastest bows I own. I was fortunate to buy them when they were half the price they are now.
I have never had an issue with them or Mike Palmer, and in fact he is very knowledgeable no doubt, but was quite friendly when I called him. His wife even gave me his cell phone number and I called him while he was hunting. I can assure you that I would not be as nice as he was.
In fact, when I was at Denton Hill my Palmer was chronoed the fastest bow for the few days I was there. That was a 58 lb bow.
I waited a while for my second bow, but to compensate for the wait, he upgraded my limbs to the Trad Slam without cost.
So, would I pay that money for a Palmer, it all depends on your available resources, but from my experience they have been excellent bows, and will shoot with the fastest out there.
