Alrighty, here is where we stand thus far...
We have determined that Sven does not want to be the fourth in a group with Jon, Peter and me. Pity. We are good company.
Beyond that, I have compiled the nominations from commenters here, Twitter, and Instagram. The front nine is below - our pick, and then the alternatives (our runners-up are *ed). I invite and encourage you to create a Modern outward nine that is greater than ours from the choices below, or add other holes from your playing experience. Remember the 2 rules (if you care to follow them): 1) you have to have played the course, and 2) only one hole per course.
If you really want to be a superstar, take into account balance of difficulty and the flow of the holes vis a vis par, uphill/downhill, direction, etc. and share the thinking behind each of your selections.
Looking back on the front nine that we did, I can see that we tended to pick difficult holes, although that was not conscious on our part. What was conscious was avoiding holes that were boring in favor of those that were memorable and thrilling to play. Especially given that we have only played some of these courses once, Tom's observation that the holes that stand out tend toward the extreme of design was astute.
