So I checked out the Powder Snake, I feel that 156 might be to long for me:P
They have a 153 model.
For boots... well that really depends on the shape of your feet. I have regular width toes, but my ankles/heels are very skinny/narrow... and for that I *really* like Nitro boots
. I don't know what boot size you are currently. You will really need to try them out (the website I linked to has free shipping and very easy returns with full refund).
