I've been healing as a holy paladin ever since I started WoW back in October of 2006. Ever since then, I went from using a default UI with grid, to even copying Muqq and Awake's UI from Nihilum and the Black Temple days. However, whenever I was able to raid Sunwell with a top guild in the US, I wanted to create my own UI. Less addons = better frame rate for me, I could process a lot better, and I just wanted to be original.
I created this just based off of what I needed, and what looked the best. Out of the multiple creations, I thought this was the best.
Just idle / creating a 25 man raid group pug for Ony:

With a 10 man group in a raid, ToGC:

This SS is purely to show how I know about my timers and what not:

In the last pic I posted, you can see Light's Grace and Judgements of the Pure next to my raid frame. For beacon, Sac Shield, and so on for my target, it's the same thing but mirrored. Timer on the left, icon on the right.
My SCT is small enough to fit between my two Unit Frames
And I don't use bigwigs or DBM anymore. I stopped back in sunwell :l Usually, the smaller of the bars would be in the very top left, and the bigger bars as a 'warning' would pop up on the left and extent out to the middle.
