If you're not a confident cornerer then I would stick to the Assegai out of the maxxis range. The Assegai has intermediate knobs between the center knobs and side knobs. This avoids the horrible dead patch that a lot of front tires (DHF/DHR II I'm looking at you) have when there is a gap/channel between the center and side knobs.
Why would not all tires have intermediate knobs then?
It is all about peak grip when the bike is leaned over. In theory having a gap between the center and side knobs allows the side knobs to dig in better and will generate more peak grip. Whereas with intermediate knobs, both these and the side knobs dig in at the same time, but to a lesser extent, hence generating less peak grip.
What will you be able to notice when riding?
On a tire like a DHF/DHR II as you lean the bike in there is a dead patch in the grip that you need to get through quickly, then the grip really ramps up, but you have to aggressively roll the bike onto the side knobs to experience this. I've managed it a few times and ended up on the inside of the corner as the front has bit in so hard. The downside is if you don't roll the bike enough the front will wash (I actually suspect this might be part of the cause of Rob's washout in his review video) or you will experience a skittish sensation from the front as it wanders around. This can cause people to be timid when leaning the bike in to avoid the dead patch and thus never really ending up on the side knobs.
On a tire with intermediate knobs the grip will be predictable/stable across all lean angles, with the downside of less peak grip and slower rolling.
My take is that since making the switch from the DHF to the Assegai on the front my cornering has improved greatly from the confidence I now have in the front end. We aren't all world cup racers who can get the bike leaned over every time. The Assegai also works amazingly well in all conditions.
Regarding WT, I've run them on 27mm rims and they were fine.
If you do want something faster rolling the profile of the new Maxxis Forecaster looks good:
The new Forekaster has turned into more of an all-round trail tire, and it's a good one.
