Replying to Invaders or arv's?????

i saw those really good deals on sierrasnowboard and i really want to get some skis cause they are so damn cheap. but i already have 2 skis this year (stls and maidens), and it would be kinda wierd to have a third. but if i decide to get some new ones, i think id either get arv's or invaders. my stls are pretty similar to invaders so i dont know if that would be a smart choice, and i want arv's cause they seem soooo soft, and they are light as poop, and they are pretty wide and wide is good.
