I know of your score. I was soo close to topping it a few years ago on a score I submitted. I think my best on Swimming without the trick is a very high 46. I've heard low 45's are possible but not sub 45. So I practiced the trick thinking I would need it to beat the World Record. I had a decent game and had the score beat before 45 second swimming.
Skeet has always been my enemy.
As for finding HS, finding a T&F cab is probably the only way. Then find a HS board.
Good luck on your hunt!
Glad you found the TG forums!
