Are these worth having? I see them in the Cabela's archery catalog - they appear to be a substitute for fletching where the vanes are part of the nock.

There was a post on these here earlier in late Jan., I believe. IMO, their junk, don't waste time/money. I boughtem a couple of yrs ago. They all blew apart in flight or upon impact w/the target. Live & learn by others mistakes & $$ lost.
I've tried them off and on the last 5 years or so with each new bow I get. I never get them to fly just right, they're a little hard on serving, and they do break if you hit them. I prefer my feathers and vanes easily.
