I've had a pretty bad experience with hunchbacks and XL-engines. Especially with this one. While in a normal hunchback you could argue that if your right torso goes, you're out anyway, here you have a second weapon to rely on. That's why i wouldn't use XL-engines in this. To make it worse, your torso sides are nearly impossible to miss. They take hits even if people shoot for your center (but who does this on a hunchie anyway). This is how I run mine: Might be too minimalistc for most people since it only has what it really needs... and bit less, but for me it works quite well. If you like you could exchange the artemis for an extra ton of lrm-ammo.
