basically what it boils down to is do you want a ski that is a little stiffer with normal dimensions (tnk) or do you want a super soft ski that is symetrical (anthem)? i have the anthems and i really like them. they're super fun for park, really poppy and smooth. i skied the tnk a fair amount last year and they're a really fun park ski as well. they're just a lot stiffer and more deliberate feeling. not quite as quick as the anthem. like i said man, it's really just do you want a stiff or a soft park ski?
