To me instead of trying to figure out which titles are relavant and which was are tougher to win is pointless. I'm not the biggest golf fan but aren't the titles refered to as majors? And is one major less of an accomplishment than the other? I really don't know I'm not being sarcastic. But my point is if we group all the 40k -50k$ tournaments together n call them majors I do believe Shane has won more In the last 10 years as anyone. And as far as "world" titles I don't think it's more of an accomplishment currently to win the wpa9 ball then the open but I know it's harder for an American to win a tournament overseas just like an Asian or European winning the us open. But for this particular argument I don't consider Shane's lack of "world" titles from holding him back In the greatest discussion. Now if the world 9 ball was let's say a 250k$ first prize I would consider it more of an accomplishment and I am aware there have been years the world 9 or 10 ball first prize was 100$k or close to it but within the last few years it's just not the case so to me any 40k$ first prize is a major and should be viewed equally regardless of the actual title of the tournament
I was waiting for someone to mention majors...its a valid point that in tennis and golf the concept of majors exist, each has 4 titles of equal significance and a victory in any is equally regarded.
However pool is more like snooker (in terms of the tournament structure). In snooker there are 3 'majors' however the World title is considered to be far more prestigious than the Masters or UK Championships.
To qualify that, if you ask a golfer which major they would prefer to win, most would perhaps say their 'home' tournament, other than that no real preference, the same with tennis.
Now do the same with snooker, all will say the world championship and then we get to pool where anyone outside the US would say the world championship and I'd guess a large number of pro's within the US would too. Would international (and domestic) players want to win the US Open...absolutely, just not as much as the World Championships (I assume).
The pattern is repeated for any sports that have a recognised World Championship, tennis and golf don't really (yes I know that point can be debated), hence the majors concept works for them.
(Before anyone moans, I'm just using snooker to illustrate a point!)
