Well I have the 2008 5 AM and to be honest I have been thinking the same over the past two years
and looks like il be buying a Alpine 160 not that much heavier than the 5 AM
I have also thinking of making a bracket to put a longer rear shock on the
Orange 5 to increase the rear travel has the frame will take the abuse
and what I have drawn up WILL work without change of geometry and very easy to make.
But then I want a slacker head angle for the steeper downs, so Alpine 160
or a newer 5 frame has head angle is slacker with a 160 fork. 😈
In saying that Take a look at Rowan Sorrell on his Silver Bullet
