My first skinny, I used the same Brownell FF I have been using for probably 10 years. I used 12 strands and padded the loops and serving area to 16 strands. After the initial shoot-in(maybe 100 arrows or so) the string hasn't crept at all. I chrono'ed the 12 strand and the 16 strander I have been making all these years and there wasn't ANY difference in speed. The skinny did need 25gr less of tip wt to tune though and even with 1/2 as much string silencer material(I use yarn), the 12 strander was much quieter. Can't wait to get the UC and make a comparison.
