Go ahead, you're kinda splitting hairs here ... if you're allowed to use decoys, don't fret that you can afford to use better ones than some other folks. Kinda like worrying that your gun is too good or your 4x4 is too good compared to what others have and so in some way that isn't fair. If you can afford great stuff use it, don't guilt yourself about it being able to afford better than average stuff, enjoy.
