Id second the advice to go with 28-32.
Panaracers are sized small, so their 32 is like a traditional 28.
Its is a good size for all roads, and can take light trails as well. Ive even done some highly technical off-road riding with them, and beat most of MTB riding buddies.
The tread pattern is of minor impportance. you won't aqua-plane below 200mph on that size tyre.
