Coho... If you do your research coho mite possibly be the easiest fish to catch on a fly rod.. yes it's much easier than trout fishing. If they are there you will catch them.. HOWEVER! you have to do your research.. 1. you need fish that are fresh! 2. you need fish of the stock 3. you need fish that aren't getting ripped up by snaggers equipment 9-10 foot rods in an 8 or 9 wt any properly functioning reel of appropriate size. the airflo streamer max is an awesome coho line what you need however is a sink tip line that casts well and is heavy enough for the water you fish.. What makes the airflo line so nice is that it has a powerful taper that makes it very easy to cast.. it even roll and spey casts very well.. it has an intermediate head and a good running line all integrated with no loops.. What that means is that you can retrieve the fly all the way to your rod tip without any loops or bumps in the line. That's something you'll have trouble finding in a spey line.. and why single handers are better. 15 lb maxima tippet works great. maybe a bit heavy but coho have teeth. flies anything bright or flashy when in doubt throw pink. but any bright color will work.. most importantly is choosing a river the easiest way to choose a river is to find one known for coho chasing spinners.. if they chase spinners they'll chase your fly... if you show up on a river and everyone is using corkies there is a good chance you are on the wrong river or the right river but too high in the system for best results fish less than 10 miles above tide water. fish through the water quickly if the right fish are around you'll know soon enough.. i wish i could tell people what rivers to go fish but I can't not on the internet anyway..
