If you happen to need other tools, the Venzo premium bike tool kit includes a very good chain tool. At $65 for the tool kit (sometimes a bit less), it's a good value if it doesn't duplicate your existing set of tools. I have Park and Jagwire tools as well and the Venzo tools compare very favorably in quality. It lacked freewheel tools, a crank wrench and chainring locknut wrench so I bought those separately.

But the chain tool has worked perfectly, including finessing plate tension. However it lacks a replacement pin, which might be a factor for the heavy user.
