I've thought about getting a set for mine, but I have come to actually prefer heavier handles for mundane use and basic opening/closing manipulations. So I really, like my Lucha. However, I keep coming back to my inferior Schrade with the rattling pinned construction because I like the heavy, thicker handles over the lighter squared off ones on the Lucha. I don't do any tricks with my balisongs. I actually carry them to use them, and only use two or three manipulations just to get the blade out and then back in after a cut.
I still may get a set for mine as I really like the blade shape, but plunking down the extra scratch for it doesn't sound appealing right now where there are other things I want more.
