I'm not sure that you "need" a link tool in order to use any Quick Link. I think it's just a matter of getting the plates in a position to where the catch and the groove in the pin are aligned properly. I use a wire (hooked at both ends) to pull the chain together and take tension off the Quick Link when removing and installing the link. When installing the link, removing tension on the chain allows you to get the link plates aligned properly without fighting the tension from the derailleur. Removing the wire will then apply tension on the plates to keep them aligned. When not using a link tool, it's much easier, at least for me, to attach the links at the top of the chain's travel rather than at the bottom since you only have to hold the pedal and turn the rear wheel counterclockwise to engage them.

I keep a hooked wire in my tool box and another one in my saddle bag. For the road, I have a Leatherman tool in my bag. While not as easy as a link tool, the needle nose pliers uncouples the link with not much effort.
