Replying to Nordica ignition vs surface watchlifes

im about to buy new skis either today or tomorow but can't decide between the 09 surface watchlifes or nordica ignitions. the watchlifes 170 is a tad small and the 180 is to big so that is kinda a downside but i could deal since i have the 08 wtachlifes now. Or im thinkin bout gettin the nordica ignitions. they are both teh same price. any input on the ignitions or 09 watchlifes?
im lookin to get this as an all mountain twin about 60% all mtn 40% park
