the tang length shouldn't worry you, moras are basically indestructable and the destruction tests on youtube just seem a bit silly to me, the knives are being taken away from their intended purpose (cutting) and the users are simply trying to break them. You really can't go wrong with a Carbon or stainless mora, I have both and they have taken all abuse I have thrown at them, very hard battening and stuff like that, both my clipper and my Mora Bushcraft Force (same build as the triflex by the way) perform fantastically. If I were you I would get the triflex, great edge retention, comfy handle and solid as a rock. Up to you at the end of the day though.
Hope this helps
