Would play Smith + 4 seamers. I still consider Smith a batsman, maybe a batting all-rounder in one-day cricket, but is more likely to get wickets than North. (Also runs).
For fast bowling, I'd take Dougie, Siddle, Harris and Cameron.
Personally I hope Doherty plays for as long as possible. I've tried to give him the benifit of the doubt, I don't think you can judge a cricketer by one match. But I can't bring myself to consider XD as Test match standard.
Maybe we wouldn't be so quick to fill buckets with filth if we knew they had a soul. Or maybe that's what they're into. Ain't no way to get inside a bucket's mind.
