I dislike all the misconceptions about hyzer-flipping. It's a very useful shot, but 90 percent of players don't use it because (at least that I've seen) there's really no great explanation on the technique. But people on here talk about hyzer flips all the time like it's the be all and end all of golf shots.
Another misconception I hate (from experienced players) is the constant telling newer players to disc down, or only throw putters, or whatever nonsense. While I firmly believe players who are new to the game should stick to Valk-esque discs, telling newer players to go down to nothing but fairways or mids or putters is, in my opinion, a step in the wrong direction. It will frustrate new players and not help them that much. Discing down should be a technique used to get players of all skill levels past a "sticking point" and after they've already developed their own throwing styles. If s player has yet to develop any habits, good or bad, telling them to step down probably won't have the desired effect and will bore them or even turn them off the sport, thinking they will never "get it."
The flipside to that, as previously mentioned, is high-speed drivers. I see so many new players chucking Bosses and Apes and Archons and whatever the hell else they find at Dick's. Give them a Valk and they have a much better time. New players still need distance drivers...jsut not the ultra-speed ones, obviously. Hell, I have a tough time throwing them most days.
