I agree Colin that too much aperture is not a good thing; a big lens/mirror trying to reach thermal equilibrium with big temperature deltas is nye impossible!
For some reason once you go past about 12" aperture for doubles its very difficult, as seeing also really affects big scopes not to mention the secondary star could also be occulted by a diffraction spike as well!!
And the high quality Tak optics with no central obstruction is going to make it easier during average seeing ; binoviewers should help also.
Your comfortable and you stand a better chance!!
