These are the 2s 30C 5000mah Zippy that I decided to go with. So far they have had great runtimes on my E-revo (geared pretty conservatively) and all the cells stay balanced very well. I like hard-case lipos better than shrink-wrapped ones for the protection aspect of it. I guess the way the wires are placed depends on what you're putting them in, I chose these because the wire style on the lipos you linked to didn't suit my application.
