started playing this year for the first time in years, playing all FH drives and playing 18holes about 3-4times a week. I've been working on getting rid of my flutter a lot lately. I could put it out 300' every time accurately in a number of lines but i'd get flutter once the disc would get 100 ft out, flutter for 50ft, then fly fine the rest. the other day i changed my grip from the typical one finger on the rim and one towards the center to the "FH power grip" where your both fingers are next to each other against the rim. Just from changing that, I'm maxing at around 375' instead of 325' and with absolutely no flutter every time. accuracy is down a little, but w/ a little practice it should be back to where it was.
now to get the 100-175ft FH approach down w my mids, i turn it over almost everytime
