One of my favs is a Daishi with no heat sinks, and 6 RAC2's with an extra ton of armour each. Ballistics generate no heat so you just wont overheat even in desert. You can pick between armour/speed, I like getting in the thick of it so i cut down speed and maxxed my armour out. There are some good configs using glads involving gauss's and ER's. I'm still experimenting with a few of them. If you want a top notch brawler go for the daishi with 6 RAC2's. Its pretty damn good, a laser boat DOES have a slight advantage, but if your playing on a heat server you have a huge advantage as they will overheat.
