[Richter]

There are no polearms which can swing from left to right or right to left with a shield equipped.

Build looks good. Light lance is an ok melee weapon if you get dehorsed. Especially if you got an MW version. If you want for attack directions (without shield only of course), Double sided lance is worth a look. It is short, but couchable. Other options include war spear and military scythe, although those are not couchable, but longer than DSL.
