Tiger,
I don't think that there's a "perfect" punchbowl.
I've enjoyed the concept on a variety of holes, uphill, downhill, par 3, par 4 and par 5.
Montclair has a neat punchbowl at the foot of a dogleg par 5 that works exceedingly well.
It's a deep punchbowl with a two tier green the right side is open with a ramp for run-in shots, the left side is guarded by a good sized bunker. The sides of the punchbowl are steep.
NGLA's punchbowl on a par 4 is neat because there are two flanking punchbowls in the fairway DZ as well as the green.
The Creek's is the hardest of the bunch because the green cants like a Redan. The Creek also has a reverse Redan from an elevated tee on # 8 and a Redan like green on # 1, a par 4.
Essex County has a huge, neat punchbowl green on a par 4.
Morris County has a punchbowl on a par 3, although its configuration is not as severe as the others.
CBM, SR and CB seemed to like them, perhaps that's why that style repeats itself in their designs.
# 1 at Yale was supposed to be a combination punchbowl green as well.
While I've heard some architects shy away from them due to drainage issues, one has to question that motive as the 1st hole on the # 4 nine at Montclair, the 6th hole at The Creek and the 16th at NGLA don't appear to be ideal sites from a drainage perspective.
A "punchbowl" green can be a bold design, with severe confining slopes and interesting green configurations and contours/slopes.
I find them fascinating in terms of their genesis and I find them "sporty" to play.
I'd like to see more of them in modern designs.
When will the 12th at GCGC be restored to its punchbowl like appearance ?
