That's the one I have and I chose it because I am in a situation similar to the OP. However back then I was also surprised that there was no 6" collapsible as they had the 5" and also bigger apertures than 6", just not 6". Maybe because the 5" was made in 2009 to commemorate the International Year of Astronomy and up to then all collapsible scopes were big...?
