For sure a consideration.    There never is a perfect solution all is a 
compromise.   For me I wanted a single run because I see any extra  connectors 
as a potential failure points.  My Tower is crank up/tilt-over so not even as 
much of a repair or change issue.

Nobody has mentioned it here but Times makes a LMR400 Ultraflex.  A possible 
solution.  The slightly increased loss on 50MC maybe about equal to the extra 
connector loss.    Another cable I have been happy with is this:

A ham owned company that has been very responsive to requests.   Of my 7 feeds 6 
use it and no issues and a few pieces are getting close to 8 years old.
