Great Mech in games, fun mini to work on (need to get another sometime in fact)... one of the games' true gems. It's far more effective than the sum of its parts suggests- if you want to hunt down scouts and such, this is a great choice. With the neighbors' love of fast-cav heavies and mediums, it makes sense for the Capellans to brew up something similar- between the Jinggau and Lao Hu (and the Men Shen, of course), they've definitely met that need.
A player in a long-ago campaign was able to install a salvaged Clan Gauss rifle in place of the standard one, using the leftover weight for ECM, TAG, and a Clan flamer. I hated fighting that thing.
