The Cabrinha custom has no spot for handles. It's a wake style board, so there would be a beat down if you rode boots with a handle. http://www.kiteworldmag.com/gear/cabrinha-custom-136/
The Cabrinha Custom 136 is also not a beginner friendly board at all, so you are smart to get rid if it. I'm not much for outing other dealers online, but curious who sold you this board. See below for my email.
It's made to be ridden mostly with boots and has more rocker, so it's going to be hard to ride.
I have quite a few boards that would work out perfect, but need more info please. Please send me an email to firstname.lastname@example.org
and we can discuss the details. I might be interested in that board and I'm a Cabrinha dealer.
