So... I'm going to click on "Yes, but I'm still going to call him Drag Strip," because there isn't an option for, "Yes, and I'm happy to call him/her Shadowstrip."
I for one actually prefer Shadowstrip to be a separate character from Drag Strip instead of just some 'random' repaint (which, let's face it, G2 was). I was on the fence about getting this toy, but seeing it being a different character sealed the deal for me. I understand that others prefer to think of Shadowstrip as just G2 Drag Strip, and hey, that's a thing you can do if you want to do it (just as I refuse to call Decepticon Runner by that name and only ever call him Barricade).
