With smaller rods like ice rods under 34” I prefer to have no reel seat. This way you can attach the reel you pick in the proper spot to balance out the set up. I prefer to use inline reels on most of my ice rods and they require being mounted farther forward and little to the side to have your rod balance correctly. If I choose to put a spinning reel on that same rod I would mount the reel father back and inline with the guides to get the proper balance. If you had a reel seat you would not be able to place the reel for best balance. On my dead stick rods and long ice rods I prefer a reel seat. If you were using a baitcasting reel, sturgeon, lake trout, or x-heavy rod it should have a reel seat. I like to use friction tape to attach the reel. Friction tape only sticks to itself and has no adhesive.
