like i said 'unless your riding in rain or comps' don't believe it, get so much more bite using tar alone. i use koxx bloxx with the TINIEST bit of tar. i might as well eat it and breath on the rim. can't say that i've experienced much slip in damp (say after rain) or any slip in dusty conditions. i will admit modulation over bite is far better than tar alone. don't think i explained my self enough. i can clearly see the advantages of using a grind, just not all the time! *but surely if your using grinds all the time you become dependant onit so making you sloppy when it comes to bigger gaps/hop-ups. to put it another way, you don't get used to landing ontop of an obstical, more playing with tyre edge. if you don't use it all the time, when you do use it your a better rider for the experience. kinda the same with brakeless riding.* never seen rowan use a grind and look how smooth he is!!!
