Really??? I love mine.
I have been using one for the last 19 years and have done hundreds of arrows in that time.
I have done 3, 4 and 6 fletches, no problem.
2.5", 4", 5", 5.5" fletches, no problem.
Vanes, no problem.
Natural turkey feathers, no problem.
"Production" turkey feathers, no problem. Spliced feathers, no problem.
Carbon, Aluminium (all but the skinnest size), Wood (5/16", 11/32", 23/64", parelell and tapered), no problem!!
Quick, clean and compact to store.
The only consideration is you CANNOT do RW feathers in a LW jig (and visa versa).
I would highly recommend one!
