Conflicting info on 130 to 150 tire swap

[copperhead1817]

Researching data on the 2006 1600 Classic rims 16x3.0 front as opposed to the Nomad which as far as I can find out are the same, does anybody know why Metzler recommends the 130 and not the 150 although they are the same rims for upgrade? The forks are Classic 41mm-Rake 32 degrees and trail 6.6inch The Nomad 43mm -Rake 32 degrees - trail 7.2 inches. Now are these minor differences a deal breaker for a 150 upgrade from the 130's? I have new Avon Cobras 180-150's that I'm ready to pull the trigger on and get them ordered but I'm getting so much conflicting information on the fronts that now I'm wondering if I should stay with the 130's although the 150's would look so much cooler for my mod. I need first hand experience to sway me for or against the 150's. PLease help. The 180 rear is not a problem according to Metzler charts.
