Teague or Imco?
 

Who have you had better luck with for drive parts? As far as I can tell the prop shafts aren't much different except Imco makes a 1 7/16 (probably overkill) and Teague only goes up to 1 1/4. Teague claims their vertical shaft is much better because it is "torsional", has a little flex in it. Imco doesn't make billet top caps, they say they don't really do much.

I'd also like to hear opinions on drive showers, Imcos shower cap is pretty but wondering if the Teague billet cap with their shower would be the better option

Billet marine top caps are nice and strong. They also are set up so you can feed water through the LWP and out the side of the case to the cap.
