Tough taking a file to a reel that goes for $175+ but, unless you can replace the bands (maybe Orvis uses a band that's a bit bigger because their reels have feet with a high instep), or are willing to tape the reel down or go to another reel, it's not much use to you; I'd do it. Maybe check with Orvis to see how much a replacement foot would cost (I'd guess a fair bit of change) before you try any modifications.
