LOL keep your hands off my yellow keycaps !!1!1
There is some merit to having a TKL from an ergonomic perspective as your mouse arm is not bent out from your body as much. As long as you don't need a numpad, I'd say go for it. I have both, and would definitely consider going TKL again.
And, as you are probably aware, the yellow Filco is available in TKL too. I hope you can manage to get one, my search (in Australia meh) has been fruitless so far.
It is a nice yellow - no-one else does a yellow quite like it.
Oh, yeah, and welcome to Geekhack
