If your intention is to use it hard, pass on the G10 model, it has next to no liners to reinforce the handles. The original model has full length and full height liners, this is a knife for hard use and of the two, worth every penny that you'll invest in it.
For the XL Espada, I have the G-10 version.
The blade will break before the handle becomes an issue...seriously.
Chopping through a hawthorn tree to make a walking stick, the blade edge got a ripple in it that had to be pounded out with a brass hammer, and then sanded a
bunch to get back to pretty much normal (some of the ripple is still there...whatever, I bought it to use, not to admire).
If you try prying, that blade will go "SNAP!!!" before the handle is fazed at all.
I have the Large Espada in the polished G-10 and aluminum handle, and it is very nice...much nicer,
But the blade is the limiting factor in either, not the handle material.
Buy the polished one if you like it, and because it won't rip your pants apart as much.
The strength of either handle material will exceed the blade though.
