Should have used averaging in the mid to high 300 yard drives. makes all courses easier.
Restate it again westie. I have an R1 and play a L81 Nike ball. I ding a fair amount of my drives. At Merion, IF I happen to be on a hole I can take a full drive, it generally translates somewhere between 290 to 310. Hole #4 and a couple other ones that are downhill or you can find the speed slot on the fairway, maybe you can hit 340. Then there are par 4s where if you hit full driver it will get you in the krapper lie #s 1, 7, 8, 10 and 11... It sure ain't St. Andy's that's for sure.
Which sorta illustrates, quite bluntly if I may... that you have no understanding of what it takes to go low at Merion. Really the drive length is the LEAST of your problems. For a top player on a par 4 or 5, they should be downrange high 200s or low 300s and on the short grass 9x out of 10. THAT'S A GIVEN. But if you can accomplish this, it pretty much guarantees you nothing but a bag of doughnuts.
If you learn nothing, learn this: 95% of the game is a combination of how tight to the pin you can get your approach shots and how well you can drain the putts.
