So I've installed the some smoothdrag washers in a couple of my high end reels, a Calcutta 200D and Zillion TWS. I installed them both with what I would consider a fairly light coat of Cals drag grease to all the washers. Afterwards I found that although the drag was smoother they both had noticeably weaker drag strength throughout the range of the drag and when I want the drag to have some strength to it I have to tighten it almost to lock down. Could anyone take a guess at what the problem might be?

too much grease? depends on "how little" you put on there. 

Cals grease shouldn't weaken the drag. The main purpose of grease on a drag is heat dissipation which is a non concern in a bass reel. I run Carbontex drags dry 90% of the time. My guess is you used the wrong kit or misassembled the drag stack somehow. I've installed hundreds of their kits without a single problem.

100% of the time for me.  I experimented both ways enough times that I was able to decide I prefer them clean and dry.  I have Carbontex in all my reels now except my Tatula's.

I am certain they weren't installed improperly. I guess the only logical thing to do is see how they are without grease.

I run mine lightly greased. Im usually fishing light line and prefer a smooth start up over max drag pressure. 

I've noticed this as well.  If you want max drag you should run them dry.

Ensure that drag spring washers are either this way ( ) or this way )(
