Paul , yes selection of targets is my main interest. I predict the following though despite that the scope is probably very good
1. A high f ratio will limit the depth most people will use it for, for a number of reasons including mount, so as said the glossies will be the targets.
2. Given general movements in scope purchasing, there is a trend to try to get a better scope.....or camera Resulting in a rerun of the glossies
Don't take it as a personal issue it's not, and having seen results from the 8 inch it has every chance of being a good scope,
Witht the gear you have I couldn't see any limitations to what you could do.
