I personally have a 5wt 8'6" TFO Signature Series 4pc for chucking dries on the Bow and absolutely love it. The guys over at Fish Tales HIGHLY recommended it for that purpose. A couple of them even use it for their Bow River dry fly rod. I believe you can pick up the 4pc for about $220.00
I've tried chucking dries with my SAGE Launch, which is a 9'0" 6wt, but it just doesn't have the same feel as my 5wt does. I use the SAGE for nymphing primarily and then bring the TFO for dries when I start to see the snouts popping up. Saves time in changing all the gear over.
I have also used my 7'6" 3wt TFO Signature Series on the Bow, before I got the SAGE, and liked it too, but it is better suited for the smaller mountain streams, which is what I use it for. Last couple of fish I hooked into with the 5wt would have blown up the 3wt....lol
