I don't own the armor parts, because I don't like the way they look, so I can't comment. All I know is that I like the way Alto's looks with the packs in Gerwalk and that awful solution for stability forces it to be locked into a single position plus I noticed some Massive flexing at the little wing hinges and felt they weren't safe to leave on. In addition, it doesn't necessarily matter if your 25 is used or not because my wing parts were loose on both the Alto and Michael and I don't own any Armor or Super Parts for my Alto so there wasn't any wear there. I didn't even want to leave them on in fighter mode personally.
