Also looking for a mod that makes the arrows shoot fast...because arrows do shoot fast. Is there also a mod that allows you to impale an enemy to a wall with an arrow (shot from a bow)?

I don't know about impalement, but you can set arrow speed as a tweak in your Bashed Patch without needing a separate mod for it. Under "Tweak Settings", I believe, when building the patch.

I don't have Wrye Bash/Bash Patch.

You just need to change the fArrowSpeedMult game setting, which is how fast an arrow flies per second in Oblivion's internal units. 64 units = 1 yard. I have it set to 3200, which is 50 yards (150 feet) per second.

Edit: FYI the default is 1500, which is a ridiculous 70 feet per second!
