Replying to 4Frnt MSP, need advice before Fri.

So my shop is going to hook me up with a sick deal that i dont want to pass up on some 09 MSP's. But, im really concerned about the "dual sidecut" and mounting. They say its recomended center mount, is this true center or core center? And will they ski switch well with the wierd sidecuts? Im not sure if i can pass up the deal anyways, but i really like the kung fujas also so im torn, basically either pair is 550 bucks, which is a good saving on the new MSP. let me know what you guys think, thanks.

Oh yeah, im about 5'10" 190lbs and going with the 181.
