I think anymore than 5/16 is probably overkill for general use. The .275 of the Scrappers strikes as a great compromise between such exotic monsters and .25 which to me has always been the gold standard for 'heavy metal'... I always loved the Trailmaster and would have bought a stainless one but for the fact they discontinued the 'AUS' one and made the warranty a meagre 5 years...
