Reviewing in forge plastic- my very first throw with this disc bombed down a fairway on a hyzer flip to slight turnover, went about 375 feet, and ended up being a birdie that I rarely get. From then on this disc has been nothing but awesome. Easy rollers that can go a long way, hyzer flip forehand shots in the woods, and more. The plastic is also excellent as far as grip and durability. Hands down one of   the best understable fairway drivers out there. 

The Function is an interesting disc to throw. It is very flippy as the numbers would suggest, but it also is very glidey. To be able to get use of the massive amounts of glide, you have to get a hyzer flip just right, or it will just burn over and crash. You can get great distance if you do get it right though. This would be a great disc for beginners who are starting to gain more experience, as it would definitely add distance to their game. The Function feels great is tons of fun to throw, but I don't think many people would find it super practical.

definitely a disc that anyone can make use of, beginner arms will probably be able to get a straight flying hyzer flip out of it but I'm using it for big panning turnovers and it's exactly what I needed out of the box.
