i really like my schwalbe fat alberts a lot. i do not run the tubless version (it's clyde thing) but at low pressures (for me, about 33-34) they are great. running them lower can only be better. schwalbe has a lot of offering and the fat alberts are only one of the many that look like great NJ options. can say that they are the fastest tires though...
edit- i just saw the new tire (on-line), the muddy mary. a 2.5 love fest! i'd love to try one of those bad boys...i'd look like i was riding a motorcycle!!
