agrees with pokerfish.
Just my 2 cents. Most spey rods are too heavy for the bow. I don't find myself enjoy fishing a 5/6wt spey rod all day. I found a 3/4 switch/spey rod is more than enough for the bow, in turns of nymphing and swinging.
The thing is, most fly shops want to sell you 5/6/7 wt spey rod, I have no idea why.
