Here's what I use as my 1x. The quirk about this variant is it's top speed and you should really take advantage of that, especially considering it lacks JJs. This is basically the build I use (my not be 100% exact, don't have MWO in front of me):

This is a bit of a sniper build. The idea is to use the speed and mobility to move to optimal positioning. With the agility that this mech has, it's pretty easy to move out of cover, pop off a dual shot or two, then move back to cover before the enemy can respond and while you're waiting for your weapons to recharge. If the enemy closes, the ERPPCs allow you to still do damage at close range, and you have the speed to get behind them, get away, or make yourself a very difficult target. The range of the ERPPCs is somewhat important to the build as it allows you to put damage down range before many opponents can even respond. Throw an extended sensor range module in it and you can be a makeshift scout in a pinch, and put Seismic on it in case you have to brawl.
An arguement can be made that with the arm mounted PPCs and no back-up weapons this build is vulnerable to being "disarmed", but with the really small arm profile on this mech, I think I've only ever lost both weapons once.
Heat efficiency leaves a little to be desired, but I can usually squeeze off 5-6 double blasts of PPC goodness before I get into dangerous heat territory, at which point I can switch to chain fire to cool off for a bit. (Pro-tip: I have both ppcs grouped to both mouse buttons, mouse 1 set to fire both simultaneously, mouse 2 set to chain fire so I don't have to worry about fiddling with the toggle mid battle).
