Get the very first driver from
Vibram Discs, the
Vibram Ascent. This driver flies straight and true to the line you choose. Any level player can utilize its speed and stability. It's a "Goldilocks" disc...it's not too fast, not too slow, it's just right. It's not too understable that you'll "dump" your drives and it's not so overstable that you need a cannon just to straighten it out. It's just right.
If you need a long, straight flying golf disc, the Ascent has got you covered. Thanks Vibram!
