I think same point-cost, 5+ unit size would be enough for me. Longbows would be alright, but I don't really think I'd be using this unit for shooting so much as rushing war machine crews, march-blocking, and diverting chargers. Honestly I'd probably like an option for additional hand weapon (pistols would be best, but that'll never happen and wouldn't make sense) more than anything to make sure the crews go down.
