I come from an era where one tried to keep weight down so I lean to the eight inch, as I have done.
I may consider ten inch if a permanent set up for a variety of reasons.
I like to baffle my tubes have extended baffled dew tubes, four scope rings in stead of two...plus I will add something to beef up areas of perceived flex in time, add camera and filter wheel, guide scope and a optical 70mm finder viewer with a illuminated reticle...my point is it all adds up.
But these days one seems to get away with the help of guiding and short exposures.
Heck...buy the big one you know you wont be happy unless you do.
Good luck.
