Nylon or Metal wing bolts?

[Pilot Ben 28]

Wanted some opinions on this, as it's something I've always questioned. Now, I get the big M6 nylon wing bolts on a trainer, the idea being that in a low speed crash the wing falls off, minimising damage. On a u/c I get it as well as during a hard landing they will snap off saving the underside of the model being ripped out.

The reason I ask is that I have a weston mini hype, a very fragile plane, and one that I feel even a hard landing will mess up! To give you an idea the u/c is held on by 2 servo screws and the fuselage walls around the canopy are made up of one inch wide 3mm ply. I don't see much practical use for the bolts in a crash with that plane and more to the point, it's a 3D model, and I've ventured up to high rates and I've seen what it can do for a "baby" 3D model!

I find that I'm always conscious of the fact that when I'm doing a manoeuvre such as a blender (of sorts) or a tight flat spin, the whole wing is held on by an M4 nylon bolt? I'm thinking of putting a metal bolt on, but is this a wise idea?
