Enlarging the hole has been tried before, in 50’s or so, according to my dad ( in Melbourne Australia) The impact was much slower play because golfers were reading greens from much further away.
My view is if something has to change, then limit the Driver head size to something like 120cc or whatever.
The balls not the cause. The 70+ yard increase in driving distance in the last 30 years comes from COR, longer shafts, and oversized heads allowing athletes to jump out of their socks to hit it. Bryson will not be the last person to long drive a Major.
