I don't frequent these forums much anymore, but the answer to this question is yes! Pretty well the only way that I now spoon fish for steelhead, etc is with my pin rod. You need a well running pin (I use jw young reels; my Campbell's work OK, islanders are a no go). I run braid because I prefer the no stretch, thin diameter and the fact that if you do rat nest, it actually tends to be easier to fix than with mono. I run a 6wt rainshadow switch blank converted to a pin rod. I find the 6wt far easier to distance cast compared to my heavier switch rod or proper pin rod blanks. You either need to bat the reel hard with your thumb, or Wallis cast. At this point, I can cast a 2/5 ounce spoon on its own almost as far as I can get it with a spinning rod. There's no better way to fish metal imo. So much control of depth, gear feel, direct contact to the lure/ fish (without terminal tackle swing or line drag), hand to hand single action battle, and insane grabs.
Of note, I've pretty well stopped doing this for coho for jig fishing or spinner or spoon fishing where a constant retrieve is needed. I just found the amount of reeling and the speed you need to do it at to be cumbersome. You also tend to miss a lot of grabs retrieving since you can't pick up that momentary slack fast enough. After a few days it can kind of mess with your wrist. The spoon on a pin is most effective for swinging for sure.
