I tried the Trial Orion IIC-A and was surprised by the punch of the LBX20 and 4x Artemis SRM6. But for me it felt a bit too slow at 77 kph and the weaponhardpoints are combined in a way I don't like. At least the LBX20 in the torso can't follow a light mech as good as I wish it would.

This is the first time to use a LBX20 for me and I wanted to make it work. So I took a look at my mechbays and found my long forgotten TBR-S:
TBR-S: LBX20 + 4x Artemis SRM6
It moves 10 kph faster, has jumpjets to get near the enemy as fast as possible and only the not used arm lacks armor. All SRMs are set in the torso and easy to target, while you can track an enemy with the LBX20 in your arm. But it lacks ammo with only 3t for each weapontype... sometimes I really wish for another SRM volley...
Do I miss anything the Orion does better than the TBR? Or might I miss a mech, which can combine LBX and SRMs even better?
Feel free to comment and improve my build.
