Thanks for the +1 miggolfer, re: the hole in ones, regards the difficulty of those shots, it largely depends on the type of wind/breeze (tail wind/breeze can be more tricky than a head wind) and course, at times there quite easy even on champ, with champ it is true what is said there is quite alot of in-air ball deviation, thus flop shots are very rewarding, regards the par 4 hio's there very, sometimes very very difficult,..I dont bother with practice - when I was trying those..id play a round or a front/or back nine stop at a specific hole ace it and move on...some times thats acheived very quickly the one on ahernes Esker Fields was a kind of bit lucky tbh, it was a punch drive over I think 340 yrds, it got a good bounce and skipped across the green at speed, I tried several different shot types on that course/same hole with trying to get the ball to drop on a specific part on the near bunker and let the ball land on a specific part of the green, and let the ball roll to the cup, (old Johnny Aherne gave some brutal greens on that course..lol..but its one of the finer real courses on here - and its super fun-) I got with 6 inches a few times after "alot" of tries, some of those are super rewarding when get that specific bounce and hear that cup sound !...Ill check out Adelades course when time allows (great designer -great at handicapping courses and the technical accuracy of holes it seems..)..when trying those shots,,depends of the distance of the hole of course, opt for a straight/or punch(and make very small adjustments to shot setup -and keep an eagle eye on the wind meter)..thus there's more control over in-flight ball deviation..regards the overswing that typically will generate the necessary back spin needed to the decelerate ball on the bounce...the slam dunk hio still eludes me...last weekend.. I was trying to replicate Ryan Moore's slam on the the 17th at Sawgrass(with breeze)..to get that stick sound in conjuntion with the ball entering/and "STAYING" in the cup, super difficult/super tricky ...Ill have another go next weekend..

... it would be great if someone uploaded one of those SLAMS...its a pleasure trying those shots tbh, because Links2k3 physics are so good...
