RG58U vs RG58A/U

So I went to come up with a quick run of coax to get a j-pole outside
and looked through three 50 foot chunks I had.  Two of them were RG58U
and one was RG58A/U.  I had nice ties on the RG58A/U and the RG58U had
tape on it that had gone sticky and I was going to have to clean up.  So
because of that reason I chose the RG58A/U and I stuck the first end
onto it.  I figured tomorrow I'd run it and finish things off...

However...  I just got to reading about it and while the RG58A/U has
similar specs its billed as only being normally used for the old thin
net networking stuff.  (which reminds me of probably how long I've had
this cable).  man its been a while since I wired my parents house up
with coax so that I could share my 33.6K modem over the thin-net to
multiple computers.  

Anyway is there any reason not to use the RG58A/U or a compelling reason
to use the RG58U over the RG58A/U?  I know I really should use something
other than RG58 if I'm going to be going any farther than the length of
run that would be needed for a mobile.  However at the moment the
repeaters that I'm looking to be able to get into with this antenna I
can hit with 5 watts (and the antenna in the same room with me).  Its a
just shy of 10 foot tall antenna in a room with 8 foot ceilings so its
not exactly "vertically polarized" either... ;)
