Greetings taman76,
Like you, I found this silly game late in life. I took it up at age 51 and after 9 years of playing regularly, I still do not throw 300' consistently, (nor am I likely too) although every now and then I crush one past 300'. You will get your discs out past 200' with small form adjustments.
A few things that helped me :
1. Watch lots of tutorial videos. Scott Stokely and Dave Feldberg have helped me a lot.
One of my problems was pivoting on the ball of my foot rather than my heel. Feldberg
suggested while doing my X Step, stay up on your toes. This forces you to pivot on your
heel, because if you don't, you will fall down. This one thing added 40 feet to my
throws. (Tutorials are like a Salad Bar, take what works for you and leave the rest).
2. SLOW DOWN. Do not rush your run up. You will hear a lot of folks saying: Slow is
SMOOTH and Smooth is LONG. It is all about how fast you get your disc from your
reach back to the point of release. The slower my run up, the farther I throw it.
3. Try lighter weight discs. I use a lot of Westside's VIP Air discs in more understable
molds. I also have a 149 gram G Star Mamba by Innova that I can hyzer flip out to
nearly 300' almost every time.
4. Disc buying is addictive. That being said, try lots of different molds, keep what works for
you and put the others on a shelf and try them again in a year. As you improve, molds
you might not have thrown that well may start to work for you. Over 9 years I have
accumulated hundreds of discs and I go back and try them again, if they still don't work,
they go back on the shelf for next time.
5. Use the "Ooooh" factor. When you pick up a new disc for the very first time and it feels
good in your hand and you say "Ooooh", that is a good sign that it may work for you.
My G Star Mamba is a perfect example of the "Ooooh" factor. I knew the moment I
touched it, it was going to be tasty, and it was and is. I know this sounds dumb, but it
works for me.
6. Accuracy beats distance, almost every time. On wide open courses with bomber holes,
this is not necessarily true, but on wooded courses it is most definitely true.
7. Take all advice (including mine) with a grain of salt. Not everything will work for you.
Try everything and keep what works and leave the rest. (Salad Bar theory)
8. Have fun and don't give up. The more you throw, the more you will improve. I am not
one that does any "fieldwork", my round is my "fieldwork". I hate picking up all those
discs, I would much rather just play.
9. Final advice, don't take Mulligans, keep an accurate score. That way you will see if you
are making progress. Saying you shot 2 under when you took 5 mulligans is not being
true to yourself.
Good luck and HAVE FUN. He who has the most FUN wins!
