It worked for me.
I flew with chains for the first 100 hrs - and was also new to tailwheels. I didn't really have any probs with the chains however, my 7 just seemed like I needed to stand on the rudders a little more to get it to turn on the ground. I purchased the JD steering link along with the rudder pedal stand-offs about 15 hours ago. Ground handling is definately smoother with the JD steering link. Many have raved about the rudder pedal stand-offs, however, I didn't notice that much change. YMMV
