Throwable 13 speeds don't come around that often, and a flippy Star plastic Boss has been in my bag for a while now because it is a classic OS max distance driver for a reason. I was lucky to grab a couple of First Run Rives and after just a couple of months of beating in, they have pushed the Boss out of the bag, except for when it is a very windy day. The hand feel of the disc is everything that is advertised, smooth-edged and grippy even when damp. Where it really shines is its workability. I can hyzerflip it at max power, or I can anhyzer bomb it into the sky, and it eats up the distance properly, fading hard every time. On control lines I can hit 125m with accuracy, and I have maxed it out at 140m on a distance line. I have also been trying it out as a skip approach disc, but haven't cracked that move yet! :-/
