Agreed, and some of the people that push xtp's hard do have a problem with them coming apart quick.
They are not as bad as pb's that way but they do have some limitations that give people like you and I that prefer the high end second thoughts about them. For instance my System One likes the 230 gr XTP and 150gr RS and I have to be very careful about hiting them om the rid cage only because it will penatrate about 4 inches and then it litterally blows up the whole inside of the chest of a deer has little bitty pieces in it, but with a good hit just behind the foreleg it is always a bang flop; the problem is I have had to pass on some good deer because of its limitations so I dont use it any more.
