This thread got me motivated to look through some old screenshots I had. I found this one from back in Cata. I didn't officially start twinking till halfway through WoD when I turned Vet, but I did muck around back in Cata with some 24's when one of my friends went F2P.
I did spend some time gearing him up and this was when I was showing off his newly picked up

Man those were the days, owning all the F2P'ers
Edit : Also found an old 24 Mut Rogue I used back in MoP.
Sadly I also went on to level him but had some cool fun along the way with him
And one last cool pic I found. West-Dalaran Choppers......... well, the original Icehawk and his partner in crime Nanzafear. These guys carved up opponents everywhere
Wow, so many memories when I look back through the screenshots.
