I read Warband's instruction. -35% to dmg. Not sure about speed, so let's stay with -25% to speed.
Bardiche:
swing damage 43-35%~~28, cut
spd rtng 91-25%~~68
Length: 102
Sarranid Cavalry Sword:
swing damage 33, cut
thrust damage 19 pierce
spd rtng 95
weapon length 105
Bardiche isn't scary from horseback...
And don't change it. As it says in instruction: reason why they made it like that (devs of game) are:
- you can use 2h weapons with 1h only, it would be stupid if you could swing it and use it with same power and speed...
From me: it is also to balance things out, if 2h would be such great weapons from horseback, there wouldn't be almost NO reason to use 1h except if you can't manual block and/or you are scared of ranged. even then, 1 slot for shield isn't too much...
