a 95 speed sword can be significantly slow sometimes than the others. Not if you master the left swing, but I'd pick more speed and thrust damage at the cost of a bit of length and swing damage. So I did. I use paramerion or knightly arming. 19 thrust and 95 speed was too bad for me.
Besides, length can be an issue with one handed weapons. I find the optimum length to be in between 90-100 honestly. All in all, arabian cavalry is not weak or strong. It is in good harmony with the others. I experimented with them a lot, and feeling this way.
