Is a 50* incline considered steep?

[Simon.O.]

i've got mine up to 62* a couple times, after that mine just back flips

I know how ya feel.
I have had my shocks all over the place and weights in and out of the tires, yes that is a time consuming task.
I can now get low 60's sustained on the towel but out on the rocks is where it counts. On my mates course I can pull 1 line that is near 80 before the front tires lip over and then pull the sh1tbox up.
I'll get a photo next time I am down there."thumbsup"
