There have been bombers in all eras. I've seen Nicklaus in the early '70s at a Major hit a 1 or 2 iron on a 230+ yard par 3 into a stiff wind when his competitors were coming up short with fairway woods. He had a huge competitive advantage because of his length and ability to keep the ball between the trees.
In the mid-70s, post Troon, I played behind Weiskopf once and saw him hit a 400+ yard drive with a 60 yard hook (on Scarlet #15) and a mid-iron into the wind on a 210 yard par 3 (#17) just before Jim Brown hit a 3-wood to the same green (Coach Brown knocked it closer). Weiskopf just wasn't able to keep the ball in play when he swung as hard in competition (or maybe he lacked the confidence).
As a kid I often played sandlot baseball on a field with a high, but short left field fence. To protect the cars and houses, anything over the fence left of a line in centerfield was an automatic out. Hit a second ball out and the player was ejected.
Personally, I think that bifurcation is the answer to a problem which is not existential to the game. But if it really bothers so many one-set-of-rules purists that a few guys can rip the ball while keeping it in play, paint a line at a radius of 300 - 325 yards from the tee on selected long holes and impose a 1-stroke penalty via a local rule for those who hit past it. It would be a silly rule as are most of the distance arguments continuing since the days of the featheries, gutties, haskels, and so on.
I do like the idea of speeding up the game via a clock or other means. But in addition to limiting the use of detailed notes during play, I'd like to see the role of the caddie greatly reduced to just carrying and cleaning clubs, tending the flagstick, and tidying up the course. I'm good with scopes sans slope and other functions, and a "normal" course guide with a few scribbles.
