had both....the ripsaw changed lug design from good to worse by adding fingers at end which flex and take away that length of bite from lugs....years ago before this change I would of told you ripsaw....not anymore....now cobra....the lug designed by the computer is far superior now in take offs and stopping...the scoops allow the track to function as good as studs but without them....id do the 1.35 cobra on a 137 unstudded....I am running a 137 x 1.6 unstudded cobra....came off a 129 x 1.375 ripsaw unstudded....22,000 miles on unstudded 1.375 ripsaw testing.....now about 1500 miles testing on 1.6 cobra unstudded...can tell the difference already and some has been on sheet ice...never spun out or got squirrely....performed really good and wont be going back to ripsaw....my 2c
