Heck dude...I have a set of Smallblock 8's that are less than 2 months old that I'll sell ya for half price just so you'll love them that much more. They are 2.1" Dual Tread Compound tires that weigh in at around 495 grams each. That's over 1/4 lighter than the Panaracer's. Saving rotating weight really makes a difference.
Get some of those Kenda Ultralite tubes and you'll be able to accelerate like a Hemi 'Cuda!
PM me and lemme know if you want them.
The only reason I'd get rid of them is b/c I plan to put some 2.1" DTC Kenda Nevegal's up on dat thang. I ride alot of trail and a weenie bit of street. I prefer a dirt tire.
