Ive shot a whisker bsqt for 6 years now. I have vertually elliminated the fletching damage by applying a little super glue at the leading edge of the vane. Now this may sound a lil bit off the wall, but i lube my WB with a silicone spray to reduce friction and drag, which also helps in not tearing up my 4" vanes. Crazy, but it works! It drys so there's nor residue or anything.
