I think the Vee Rubber 401 is more aggressive than the Kenda K270 off-road, close on pavement. Don't think the 401 can match the 270 mileage, but insufficient data/experience now available to make that conclusion.
Beyond waffling/stipling, my TrakMaster II front washed out on a hard surface, when I tried to regain the roadway after dodging an oncoming delivery truck after it forced me to the shoulder. Upon inspection of the tread, I saw very little surface area contact laterally, compared to a fully 50/50 tire, like a K270. I think, had I been on dirt or gravel, the TM II would have hooked up o.k.; not so much on the hard surface. I believe a Dunlop 606 or a Vee Rubber 401 would have offered a better chance in that situation, than the DOT knobby TM II.
