Those bitters are great. The small ones can be dropped right into a school without spooking the bones and the deer hair makes a pretty good weed guard. The are a pretty easy tie too. Had the pleasure of meeting Pops a few weeks ago at Turneffe Flats. That guy has forgotten more info on bonefishing in his lifetime than i have read.
C & F boxes are great because the foam slits are much more durable that standard ripple foam. If the price is not a problem then i would recomend them, I have a few and they have served me well over the years.
