So: I don't know what Master or Grand Master is. Explain please? Thanks! I am 52 years old.
Like others have said, masters are 40-49, grand masters are 50-59, senior grand masters are 60+, legends are 70+ if I'm not mistaken.
If you're getting controlled distance in the 300ft+ range, that's actually very good, congrats! You'll be competitive in the grand master division. As a grand master myself, the tournaments are won and lost on approach & putting. Sure you get a guy once in a while that will birdie a 450ft hole, but usually it's a battle from 100ft in. lol...
My controlled distance is pretty much the same, anything up to around 310 I can usually park within a 30ft radius of the basket. Anything further and I'm throwing max distance lines, a little higher, a little more s-curve, etc. Controlled shots are usually lower, straighter, etc. Or perhaps they are low controlled hyzer skip shots, etc, etc. Mid ranges, fairway drivers, etc, etc.
"I got farther distance (consistently) with the Daedalus and the Katana, but could only throw those on extreme curves and had a lot of difficulty controlling them."
Describe the flight path if you don't mind. These are max distance drivers that do better in open fairways where you're not really trying to park it, you just want a chance at a high percentage par or low percentage birdie. When thrown with no wind, and enough power, they will usually flip up (re: hyzer flip) fly straight and then sweep to the right a bit, and finish back to the left. Classic s-curve pattern. Any headwind will cause them to flip over to the right quicker or become a roller. A tailwind can get you a little more distance as long as you don't throw them nose up and cause them to stall out. I have 4 Daedalus's in my bag, 158 to 175. I use the heavier discs when there is any kind of wind or if I need a stronger finish to the left. The 158 version flies on a long tight s-curve for me, never want to lose that disc. lol... Btw...the Katana likes to fly a little higher, where the Daedalus's work better when thrown lower. I try to keep them around 3-8ft off the ground.
