I bought six 500s, and they are awesome. I am actually shooting the Yumi 400s by Three rivers and like them a lot. They are just slightly thicker then the Barefoots, but also very skinny. The 500 Barefoots are very skinny. The problem with the skinnies are the aluminum inserts. I replaced the yumi inserts with black eagle instinct FOCOS 350. These inserts are an al insert and steal outsert that weigh 100gr. makes a bomber arrow. I think Victory arrows have an insert outsert that would work for the Barefoots. that is my plan with the Barefoot shafts! the reason I have different spine for the two arrows is because I plan to shoot different point weights out of the same bow and similar arrow length.
