Hi Kim,
If you can, go with separate feedlines. You will have less maintenance, fewer
potential issues with the additional "devices" in the line, significantly more
set-up/operating options, and, more hair if you ever have to troubleshoot any
problems. The later alone is a significant advantage !! Of course, just my
opinion.
Hope to see you again at the 2020 Hamvention VHF dinner !!
