With that said, decks such as the Lib TRS are produced in Narrow.
In 148 it is 1.4 cm less wide at the inserts than the Parkboard. With some stance adjustment and perfect binding positioning/tweaking you will get very close to the ideal on one of these narrow decks.
I hate to be the one to tell you that you should not go with a model that you had your heart set on.
Well I've never ridden the Parkboard before, and as much as I like the model and TBT, I'd like to find the closest possible match for my size and style. I'll take a look at the Lib TRS.
