apples to oranges on that one... you cant go wrong either way and there's no definitive answer there as both are equally as strong in terms of cutting... gw is stronger in terms of endurance though so secondarily, i would say that being gw will allow you to perform at the highest of levels, albeit, sr9011 will also enhance performance, if you have to pick one, i would lean towards gw but there is a strong argument for sr as well... sorry if that is not more conclusive of an answer but its that close... mk2866 would be the next addition if you wanting to add between that and lgd...
