That sounds like a better solution Matt. I tried the 43mm to T-2 adapter with the T-2 to 2" female adapter and could not get infinity focus with a 2" mirror diagonal (on the FC76DC).
Using the Baader prism diagonal with the T-2 to 2" female adapter I was able to get focus using various extensions. I also found that the Takahashi focuser felt a bit overloaded with a 21mm Ethos and even a 17mm Nagler. It worked ok but it was much smoother with lighter eyepieces such as a 27mm Panoptic and a 40mm GSO reverse kellner.
I think I will mostly stick with 1.25" eyepieces for the FC76. There may be occasions when it will be handy to have the 2" eyepiece option but I think the focuser is generally much happier with lighter loads.
