Tire help needed, I'm lost looking at them

[derf]

HELP!

I've been studying tires for a week now, and I am more lost than ever. What I want is a knobbie that lasts 10,000 miles. Knowing that I will never find one...

90% of my riding is on road, with most of my miles being done on either superspab or twisties. But I have grand plans this summer to do the trans NJ trail, the trans WV trail, plus a trip down to NC, and a few other smaller trips. I expect to do about 10k this year on the KLR.

What I want is a knobbie, what I need is a street biased dual sport tire.

I've been looking at the:

Avon Distanza
Conti TKC80 (what kind of life from a knobbie 6k mi?)
Michelin Anakee 2
Pirelli MT90 (cant find the right sized rear damn it! will a 120 work?)
Gripsters (what I have now, looking for a little more off roading ability, but it really is good in the corners)
Enduro 3 Sahara (good tire but has short life span)
Tourances (yay except for price)
Conti escape (yay except for price)
D606 (knobbie, good price, low mileage)

Like I said I have been searching and searching trying to find something that makes one tire stick out over the others and I'm just not really seeing it. Money isn't too much of an issue (I dont want to spend buku bucks on a tire that wont last long) but it is a factor.

I guess I'm just looking to be steered in the right direction, I really like the idea of the MT90 but that 120 vs 130 is my concern. Any help is appreciated.
