Hi folks,
I have a Hydrogen 3 wt, along with an original Dually 4 wt, and a Beulah Plat 5 wt switch. I got them all for trout spey fishing. When I was trying to make an initial decision about what rod to buy (maybe 5 years ago now) I had the chance to use a a Sage One 3 wt for a day on the Missouri River. The Sage rod was sweet, but at the time the cost pushed me into a lower price point rod, so I purchased the Hydrogen. I paired a Rio Max Short 275 (20ft) head with it, and now am trying a SA Adapt 280 (22 ft integrated head). The distance was just somewhat better with the Rio, mostly I think bc the Amnesia mono running line shot much smoother. Reason I went with an integrated line was the head and mono junction go hung up on the single foot guides of the Hydrogen (the only thing I don't really like about the rod, but the SA line fixes that nicely). With high water, I've recently been throwing a 10 ft MOW tip (7.5 ft T8) and a two streamer rig (size 4-6 sparse streamer flies) with the Adapt. It works, but the rod would prefer 5ft T8 instead.
Weight wise - my Hydrogen 3 weighs in at 3.9 ounces.
I've landed all flavors and sizes of trout on the Hydrogen, including up to a 28 inch bull trout. It's fun with a 11 inch trout and exciting with a monster (I had no doubts about the rod's ability to handle that large bull). The 2-5 lb fish in your river will be very fun on that rod.
That was a cool video of the Sage HD technology. In the video, Marcus was hucking some nice casts and tight loops. My loops not so much. But, in my case I suspect it's more the caster's fault and not the rod's, lol! A question to ask yourself - is max distance with a trout spey all that important? IMHO, not as much as presentation is - and it's easier to manage the presentation with a shorter cast. The Hydrogen will cast fare enough.
The Hydrogen 3 wt will certainly get you well into the game for short money. And if you don't like it or wish to trade up, the Hydrogen 3 wt seems to have a bit of a cult following, so you could find a buyer fairly easily.
