All right guys I am going to be building up a XC ride for some dirt road and single track riding.I am 5'9" tall weigh about 225 dressed to ride. I don't do anything too extreme but need a big guy friendly frame. I am looking at either a 17" 2006 600HT or an 18" 2007 Fantom frame. Which one would be the best for my size and type of riding? The geometry between the 2 frames seems to be just about the same and is almost the same as my current Giant Rainier although the Moto's have a longer wheelbase by 1.75".

Thanks
