I play for score all the time, always going for the GC, haven't played TZ or LOTR on location in months because you know you're in for a 10 ball game all said and done. Objectives are nice, but I can't stand being inefficient in my point scoring at any time. Sure it's boring to watch, but I turn those one-shot-wonder games into a mini-contest with myself - how many times can I shoot it before I miss? It never becomes not-entertaining as I'm constantly trying to improve my skills. Spell RIVER 6 times? Sure why not!
I'm firmly in the "defensive" camp, and super-long games bore me. I generally prefer extra balls turned off, and the idea of TOPS tournaments with 1 ball setting appeal to me.
