I have seen different Roto Razor from the website. RR 1 2 & 3 what are the difference?

ROTOrazor 1 - less light loss than ROTOrazor 2 but inferior bokeh.
ROTOrazor 2 - Probably the best bokeh of all adapters.
ROTOrazor 3 - Probably the GG that will become the best light efficient GG on the market. Still don't know the effect on bokeh though.

thanks a lot for your input. I feel a bit better now i have ordered adaptor with interchangeable GG. I can have different GG for different requirement.
