the length shouldn’t be to much of a problem.
The good thing about the 132 is that it’s your primary freestyle board allowing you to land tricks even in hard conditions, bigger and wider makes it easier to land.
Also the new construction and weight make the board even lighter than last year smaller sizes.
Regarding the 132 I wanted to find a compromise to have a great freestyle board which you could also use for bindings as it is not to small.
The bigger 138 will be for riders wanting to ride mainly boots or heavier riders wanting to do both freestyle and bindings.
I started freestyle with my 132x32 at the beginning of kiting, then got the 120x36 and kept going bigger, so I’m pretty sur ethat going bigger and wider is part of the thing in freestyle nowadays. I remember when I switched from the 123 to the 129x39 I was landing twice as many tricks because of the easy landing !
You should give it a try and might love it !
