I wou;d recomend you bring BHPT's in size 14-20, zebra midges 18-22 (black, green, grey), soft hackles, wooly buggers and scuds/sowbugs. The float you are talking about covers some good runs. PM me and I'll tell you a few of the spots i really like along the way.

The caney is a good river but be sure to check the schedule and be on the right side of the river when the water hits. It can come up quick on you. Have fun and good luck.
