It's really weird not being able to stab someone with a spear, though. In Brytenwalda, I routinely use a spear from horseback to tremendous effect; I charge at the enemy, then veer away at the last second and do a thrust at a 45-degree angle into their face to avoid their spear thrust. It's exactly the kind of mounted hit-and-run spear attack you want, but more effective and realistic.
Unrelated question: Is there any reason to use anything but the kanabo/tetsubo/etc. on foot, as far as melee weapons go? It has good reach and acceptable speed, lots of armor-smashing power, can knock people off their feet, usually brings enemies down in one or two hits, can crush through blocks, and nets you captives to sell. I want to use a nagamaki or the yari that looks like a Chinese dagger-axe, but it's impossible to justify getting anything other than that vicious baseball bat.
