Yeah when I first looked at the hand I couldn't understand why you didn't just barrel 3 streets, from previous history it seems as if there is some mistrust between you so why not take advantage of that fact. Also though your not repping a whole lot on the river it's such a bad card to bluff griff will nearly always have to give you credit, plus the 7 could hit you as a number of raggy 2 pairs, 46, are in your btn raising range.
