I hope you didn't misinterpret me (as you were referring to other people too), because I certainly don't agree that the sonar head is "Mattel like" either.
I used the term gimmick more in the "accessory" sense, it's just something that I would try out once or twice and then throw in the fodder box, as I prefer the regular look. I certainly wouldn't mind it included though. Same goes for the pneumatic wrangler that was included with the BB suit, while nice having, I've never displayed it once (it actually
was helpful for a custom, but that's not the point
).
