I personally would go with 8" [around 9-10kg]. A 10 comes in around
14.5kg + any fittings such as an electric focuser, Telrad, etc.
A mount of HEQ5 size will easily handle an 8", but most people who
use 10" scopes move up to NEQ6 size. I suppose in the end it all
comes down to whether it will remain in place, or will be demounted and
moved inside after each session, and finally, how fit and strong you are.
