Hello. I was using this mod called powerful shouts but it was too glitchy...like it would make Alduin unkillable...but shouts, as they are, are just too weak and the cooldown is rediculous. I'm looking for a mod that imporves both.

I've been using http://www.nexusmods.com/skyrim/mods/14353/? for a while, and I'd easily recommend it.

I just switched to http://www.nexusmods.com/skyrim/mods/41376/?, but I haven't had enough time to judge whether it's a keeper.

I've been using http://www.nexusmods.com/skyrim/mods/32211/? for some time now, and have been happy with it.

I use thunderchild, which is really awesome

and Thundering Shouts to change the actual sound, which is also awesome

I think mighty magic and combat remastered speech module use perks which improve shouts

There's also http://www.nexusmods.com/skyrim/mods/17010/?.

That there is.
