How is that any different from the same happening after you have turned on an out and back trip?
i don't really get the anti-ring views that are often aired. When I hired I wanted to discover new canal and a ring is the best way to do that.
To answer the question exploring the Staffs & Worcs as suggested would be good; the southern half is a beautiful waterway. Over two weeks there would be a lot of opportunity to view other things. It's lucky then that you can visit such places as Shugborough Hall, Wightwick Manor, Kinver rock houses and the Severn Valley Railway.
It might still not stretch to two weeks but there is also the option of exploring the southern end of the Shropshire Union which is as near as damn it lock free.
The Staffs & Worcs is far from lock free but they are generally encountered one at a time, the major rings all have significant lock flights in them. To many that's part of the attraction of course.
