The extra will keep for some time to top off the loop and for changes made to the loop. The Micro-Res makes filling and bleeding easy but I recommend getting the one from Performance-PC because you can order the "optional" G1/4 tapped top hole which will allow a fillport or a temp. probe to be added.
