This has been a huge topic of discussion since the Isner match so I figured I'd bring it up here.

Personally, I think 5th set tiebreakers should be mandatory. Without them, schedules can potentially be completely messed up for tournaments, and players can be physically ruined for their next match.

What do you guys think?

I beleive that the fifth set should not have an immediate tiebreaker.
maybe for the fifth set, implement a tiebreaker once it reaches 15-15.
Getting to the fifth set alone usually means it has been a great match, and ending it so soon in the fifth would be unfair to one player.

15-15?!?!? There's very, very few matches that get that far anyway.

well, yeah, theat was a bit of an overdone.
maybe 9 9.

I think the rule has it's downfall like all other rules. I mean if it goes to 6-6, what's the difference between that an 9-9? Either player has yet to break the other's, but you've added even more time onto that match that gives the winner even less chance to win next round due to being tired. I also think it can cause matches with stronger servers to be rewarded kind of unfairly(only need to get a couple lucky points against your opponents serve, then rock your own in to win a match that was very closely contested) I don't think there's an easy resolution, but to have the rule set as Wimbledon does now is just plain ridiculous in my opinion.

But as he said before, most matches dont ge that far anyway.
So when a match does get that far, it means it has been a good match.

I just dont beleive there should be a 66 tiebreaker, but maybe for first few rounds of matches,m but in later rounds like quarters on, it shoulkd be lengthend to a higher limit, as the players will have bigger breaks in between matches

I don't like 5th set tiebreaks. The number of times a match is that long is so low that you can just forget about it. The system as they use it now is fine in my opninion.

Chances are bigger the matches are delayed by rain and tennis tournaments shouldn't become strictly directed shows, let's keep the excitement that surprise brings!

12-12 and then it's optional and both players have to agree

if one doesn't agree, the match continues
