Buzzo,

Disclaimer - I haven't floated this one yet. I have heard during low water years that you may end up doing alot of dragging of your raft the first few miles. I would suggest you touch base with your air taxi to make sure the flows are satisfactory for the float.

For flies that time of year, not sure anything beats a purple egg-sucking leach and variations of it up in AK. That is always my go to fly.

Enjoy, I'm a little jealous right about now...
