depends if you want a lot of strength or like a bit of shock absorbtion-id say definitely get a 110 but a metal core is a lot stronger but might hurt your wrists a bit more than say a yak or a stock pro wheel--plastic cores will last a while in the front
I run a spoked metal core in the fount because i know that its not going to break in the front, and if i ran it in the back it would probably break, and plus having a spoked wheel in the fount makes it look cooler!
