(POLL) Which is hardest: Hole-in-one, nine-darter, 147 break or perfect game in bowling?

Recently, discussions have regularly flared up on social media about which achievement is the most difficult; a hole-in-one in golf, a nine-darter in darts, a 147 break in snooker or a perfect game in bowling.

A hole-in-one means the golfer manages to hit the ball from the tee into the hole in one stroke. A nine darter represents the shortest possible way to finish a leg, in nine darts.

The 147 break is the maximum break a player can make in snooker. This way is only possible by potting a black ball after each red ball, followed by all remaining colours. A perfect game in bowling consists of 12 consecutive strikes.

What do you think is the most difficult? Let us know in the poll below.
