Hi Suzy,
I haven't had a lot of experience with collapsible dobs, except for a friend's Saxon collapsible 8" which seems to work very well. I use a truss dob which collects no more dust than my former solid tube 12". The secondary does tend to dew up and I use a dew heater which works fine. But I don't use a shroud. If you have a shroud, there shouldn't be any difference dew wise compared to a tube. Collimation is actually a little easier on my truss dob than it was with my tube scope.
Whichever you chose, you'll enjoy it immensely. But I wonder if it would be worth having a play with a 10" to see how hard/easy it would be to handle? 8" very good, 10" very very good (provided that it is easily usable)
