244 and 270...tryed the 244...
after i just about tossed the 660R away
twice it came off with 2mm of wear..
silly little blocks flex and put very little
rubber on the ground..

Shenko 700.. bigger blocks that don't flex "as much"
side blocks are bridged to help stop block flex when
leaned... and the same applys for gravel...no grip on the marbles "stones"
the grip is in the hard base under the gravel = rubber on the ground
as it is usaly far to hard for a nobbly to pentrate so you end up riding
on the top of the nobbs...
