[Heel n Toe]

The Dean's plugs are good. I can't remember if all Dean's plugs have gold connectors/contacts, but if yours are gold, that's about at good as you can get on the connector issue.

The 7-packs are gonna give you a little bit more runtime and ooomph, so if you ever run across a decent price, get a coupla sets.

Another thing to keep in mind is that running through grass is gonna really suck the runtime down because it puts up a lot more resistance than you would think, so try not to run it in grass very often. It causes the motors to heat way up, too. It's like if you were running a mile in knee-deep water.
