as I do mostly 1/48 I pin a lot, almost everything.
Most 1/48 don't have precize mounting pionts anyway.
But if you build WnW, a very important first step is to fill the holes where the struts will be placed with a liquid mask of any kind and clean up the hole and the strut before glueing.
That makes it a perfect bare plastic to plastic connection that can be glued with something like Tamiya extra thinn or the likes, they give a very stong bond, but don't like painted surfaces that much.
A pin will give a strong bond also,so if glue alone is not enough, pin!
