Are you not using the steerer tube mount for the tool due to issues, or just because you don't need it with the larger pump?
One advantage to using the canister extension to the OneUp tool is they now make a jabber extension, AND you can put in their mini pliers and a few spare pieces of bacon in the canister.
I recommend taking a thin strip of Gorilla tape over the top of the spare quick link, to hold the links in place so they don't accidentally fall out when you're using the tool.
