Personally, I don't bother with steerable tail wheels anymore. Heck, I don't even bother with wheels most of the time.

I recently built an LT 25 and just used an old control horn as a skid. Ground handling is a piece 'o cake and I saved all the weight of extra linkages and/or servos.
Of course, if you fly off a paved strip, a nylon control horn won't last long. In that case, I'd go with a simple music wire skid. I did one on a MoJo 60 and it's absolutely trouble free. Here are a few pics of how it went together.
This plane has seen over 9 gallons of fuel so far and it still works great. It's very light and anyone can do it.
