RE:Spey Rod Size?
My 13ft 9 wt is a Thomas and Thomas. I have been using a windcutter 7/8/9/ on it. It has worked well for me on the Babine,Klickitat and Deschutes Rivers. It will fish tips around 150 grains fairly easily and handles the floater very nicely.
My 15 ft 10 wt is also the sage 10150-4 it took me a while to get this rod dialed in but i really like it for throwing my 15 ft 550 gr tip:O)
