interesting. I've bowled some longer tournaments, like 7 and 8 games and once it gets deeper into the set everything becomes toast.
I don't like solid urethane for this b/c it picked up too early.
Have a storm supernatural which can be useful, if there is an outside shot, but it it starts to hook will not carry playing deep inside. Plastic may be way to go for the total burn.
And I do think it can help to have these for practice. Especially is playing sport shot and want to practice short oil patterns on the houseshot. It's a way to get used to playing outside line
