I am back from throwing the Stalker for the first time. I try to throw straight and flat. There is a good rise on the disc. However, it seems to hit a really hard right turn (LHBH throw) after going out about 3/4 of the distance.
I have a 171gr Stalker and I love it. I usually use it on open holes and holes with dangers to the left around 300'. It is also a nice approach disc on the longer holes around 600' or more. Get halfway there and then toss this disc. It gets good controlled distance and is not flippy in my hands. A very good stable driver.
