Thank you guys,
for the 2h weapons I would still prefer the morningstar or even a longsword.
I am not using the long hafted blade anymore cause of the weird animation, it was really good as a secondary weapon on horseback but since you have to drop your lance, it's not of use anymore for me.
Also as I said in my guide and as Torben recommends, the side weapon shouldn't be too expensive, cause the horses upkeep is really high.
