The game has far less challenge with modern equipment on a modern course with modern conditioning.
Rugged, unforgiving, inconsistent equipment that allowed far shorter distances, while playing out of erratic lies in the "fairway", rough that's actually rough, bunkers that are hazards,and greens that required judgement of varying surfaces, an often inconsistent roll/bounce and a truly solid strike, all would conspire to make scoring far more difficult.
Sure "modern" courses are longer,perhaps some made difficult by the contrived water features cluttering the properties but the advances in distances gained by elites, has far exceeded course expansion.
assuming that was the question.
Some older courses(or sets of tees) would be far more fun with older equipment, but often procuring it can be expensive and cumbersome-and it can become a bit of an arms race with a lot of older/older style equipment not being anywhere close to equal or inexpensive.
A 85% ball could have the same effect for distance,but (for some),wouldn't provide the same joy as hickory,blades or persimmon
