Change gt3 timing belts for something else??

hello community,

I built from scratch what I can only describe as a routy Ox giant.
My bed measures approx 1500 x 3m long.

I opted to use gt3 timing belt when I started which has been ok, drives smooth enough but....
Has a tendency to bind if it catches anything and looses steps.

I have been know to accidentally stick something in its path on occasion.

So my belt runs inside the groove of the aluminium extrusion with steppers and cogs running horizontal to the aluminium.

What I would...

Change gt3 timing belts for something else??
