I've got a better idea than that...get ol' Rob to come down to a little place called Leland Lanes in Tuscaloosa, Ala. As of 2000, they were still laying down a completely flat -- COMPLETELY flat -- shot as their THC. Things may have changed since I last bowled there (I'm going to try it out again the weekend of April 1 when I go down to visit friends), but if it's still the same pattern, ol' Rob wouldn't be able to bowl his weight, even with no-tap rules, much less a nine-spot.
