I always hear good things about the P&P but to me they look cumbersome and stiff in all the pics...I like my old wet felt or the uglydog stuff best myself.
My P&P is stiffer... I had 6 layers put in the chest.. The dog I had it made for didnt have any problem moving or loading up in my 6 inch lifted truck with it on.. The last 2 dogs ive ran it on could barely move in it, much less try to jump or run through the woods..
I had a Uglydog guardian and devestator vest, and really liked the mobility of them but they just seemed to fall apart at the seams..
Im looking into the 4R vest now..
