He was certainly a huge fan in RTW, and it was his post on how to use them properly that made me a huge fan. I wound up playing around with toxic hippos as the ERE in BI, and his instructions turned me from having 1 or 2 units that stayed out of the way until time to chase down fleeing generals to having 6-8 units per army and slaughtering the foe with them. I hit the ground running with them as Byzantium when this game came out, and have no cause to regret it. I just don't have the time to post the guide to the Byzantine missile cavalry now while I'm at work. I can do it later this evening.
