    The Challenge GRIFO XS is worth checking out.

    i just raced suckerbrook (twice) on the XS in white. It was very dry, with alot of grass, and then a trail section with alot of nasty rocks, then a sand pit, and then pavement, finally a loose rocky gravel section. they performed very well, with amazingly good grip, in all those conditions. i was worried about the tiny side knobs vs. the pipistrello, and a freind runs those, and they are alot more supple, but these did the job very well.

    mind you, i was riding slow. YMMV.

    Dugast is out of my reach Jerry! Thanks for the feedback. I am in Philadelphia now and the climate and terrain is certainly different from Portland Oregon.

    File tread seems to be the natural answer, but I have found that the tractor tread works well in all but the worst conditions. If the course is really dry and hard, a 34 can be nice as you can run it very low and carry a lot of speed with shock absorbancy of the larger casing. Otherwise a nice and supple 32mm gives good grip with minimal rolling resistance. I am giving some thoughts to running Vittoria's new high tpi tires on my main wheels with some fairly worn down Griffos on my pit setup.

    I had grifo 32 file tread next to Dugast 32 file tread next to Grifo 34 standard tread this weekend.

    The dugast 32 is alot fatter and of course a fair bit more supple then the (white, high tpi) grifo XS. The 34 is HUGE. Pippi is more like 33 I would guess. Right in the middle.

    If I had it to do over, I would have gotten the 34xs. Maybe. I dunno. I do like em large, though.

    I ended up with the 290tpi Vittoria EVO XG tractor tread. I considered the file tread but the tubular version of the XN model (file-tread) does not comes with the side knobs as the clincher version does and I can't rationalize the cost of the Dugast. (Can anyone?)

    I use the Vittoria XN clincher (which has the same the same tread design as the Dugast Pipistrelli) on a fixed gear and it wasn't the most supple or stickiest tires but I hope that the new casing helps in that regard.

    I've got the new XN tubular and it does have the side knobs like the clinchers do.

    no -- it is a model year difference.
