I see your point, but it seems to me that more often than not you are going to miss that flop, and that just leaks money away to the higher PP that called your PFR. At least it would at most of the tables I have seen. Who knows, Obviously it conceals your hand and lets you let go of the hand really easy to strength... I dunno, I haven't really been successful when I try the LAGG approach personally, so maybe I am biased against it..
