I have trouble with Oly because I don't play it enough...
My best rounds and shots have been at Kiwiah even with the lack of putting angle pics....
Merion is tough but when you play it more often good results are very possible like Oakmont, tough courses but a real challenge...Merions back is tough but only par 34...
best of Par 3's I'm getting used to, best of Par 4's is as tough as best of Par 5's is easy...
the back 9 at BPB makes up for how easy the front 9 is....
I won't EVEN try RSG or STA with very high winds...to much calculating for my feeble mind...
Pinehurst is tough to play but easy to putt...
Cabo easiest course here...Whistler can be tough if you approaches are off...
Which brings us to Congressional, if I score decent on that course I made at least 6 putts over 15ft...none of the yardages jive with the yardages I have for my clubs....the only time I broke 60 (shot 58) my average distance to hole was 16ft....CCC doesn't look tough but I would rather play Mer/Oak/Oly anytime....
I'll pass on best of par 4's too...I think 34 is my best 9 there...LOL
