I've been messing around with one of these for the past few weeks and this is a solid product that does a good job keeping your tippet or Rigging Foams straight. I also like that you have two options to carry it with the carabineer or Velcro loop on the backside. My only complaint is that it doesn't include a round plastic disc to hold the wider openings of the TroutHunter tippet spools a bit more secure. It works as is but a disc with a small center hole might work a little better.
