Haha may be worth a try to use against sns. A while back the game owner released a list of style pairs, styles which should cover the other ones weakest matchup. One if those is gnp and snb. I believe that gnp is worse against sns than snb. However, I also believe that the popular build of gnp is much closer to right than snb. Been testing some variant snb stats to try and get around that but lately losing to sns a lot still. Given that, youre probably right that sio is a good option
