Very limited experience with this mech but so far this build is working out well for me and my combat system. The 2 Large Pulse Lasers deliver some serious hurt backed up by a Medium Pulse Laser for when you're in close. Enough heat sinks onboard for a decent cooling efficiency. The SRM-6 pack used in its effective range searches for weak spots in armor hoping for a crit. The 4 jump jets and the XL280 give this 55 tonner plenty of speed and maneuverability to dictate when and where you fight. alternate: I have experimented with replacing the medium pulse with medium laser and added another heatsink for a higher heat efficiency
Exactly what I was going to suggest. It isn't the heat penalty that makes me dislike the medium pulse in this build... it's the range reduction. I hate how short range the medium pulse is compared to a regular medium. There are very few scenarios where I would take a medium pulse over a medium laser.
Came up with a similar build with 2 Large Pulse Lasers. Accurate shooting/tracking with those just chews through armor. Once the internals are exposed, time for the SRMs. Dong very well for me when I play smart and remember that I'm in a medium mech! Just had a 5 kill, 686 damage match with this build.
