poke at range with the Large Lasers, then go boxing with the old left right power fists. All Lasers are in different heat groups so dont incur a heat penalty. You can possibly get another Micro Laser by using another chasis but i prefer the C-bills
I think you'll do better with ERPPC's instead of ERLL's: _ _ And ERSL's are a little hot and have a huge burn duration. They're okay and pair decently with some weapons, but if you're looking for a high dps short range weapon to complement the ERPPC's for when you move in for the kill, SPL and ERuL are more effective. They're cooler and more pinpoint (though shorter range than ERSL's). ERSL's you'll find are pretty difficult to get damage on highly mobile lights and mediums - but ERuL and SPL will make alot easier for you to pick out components and put damage on those pesky Commandos and Fleas.
Your builds run really hot with only 12 or 13HS, i like the range of the ER-Smalls allthought the burn is a little long as you say. I tried 10 micro pulse lasers recently but you have to be practically standing infront of them to be in range.
