I find straight through finders are only a problem on low to the ground Dobs as you have to twist your back to get that low just to look up. I used one for many years though on my 6" f5.5 Newtonian mounted on a Vixen Polaris because it was much higher and in this case a right angle (even RACI) is a pain unless you can rotate the rear (eyepiece/diagonal) end without upsetting the alignment as is the case with my Stellarvue F80M (RACI) that I now use on my C9.25.

I have a TS Optics RACI 60mm, not only can you rotate the amici prism diagonal but, it accepts any 1.25" EP & has a helical focuser... Still messes with my head occasionally though when the movement of stars through it is slightly different to the movement through my SCT with a regular star diagonal... still find myself going the wrong way in one or the other...
