Using Lensbaby for creative portrait work. Has anyone used alreay?

I have the composer, focus is quite easy but I find it quite difficult with the default focus screen on the k5 using anything faster than f2.8 for critical manual focus but the focus ring on the lens baby composer is really simple and works fine.  You get less control though with this version as you get no shift.. the older ones allow you to move the lens up/down/left/right as well as tilt.
As for the focus its easier for example to focus my 85mm f2 on my gf1 rear lcd than through the ovf on the k5, the lens baby is the same, it could just be me as I do have glass's.
