Pro is a legacy add-on for older packages that had specific traffic management. The traffic management on current products is simply a prioritisation system to ensure things like VOIP and gaming get through their in-house routers as fast as possible, taking priority over torrent downloads and the like.
This is applied at individual line level, which benefits the user, and also at network level where it should also help. Link
. In the past one user has claimed he gets better performance on Pro. However you can try it with and without, as Pro is a monthly option not subject to a minimum term.
There does seem to be a slight loss of maximum throughput, possibly on your line about 2Mbps. This thought by some to be mainly due to the buffering inherent in the traffic prioritisation system. Plusnet also apply a copy of the IP Profile rounded down to the 200kbps below the IP Profile. Some others also do similar but generally don't disclose it. It is to do with avoiding packet loss at the MSAN/DSLAM.
Re line rental, WelshWarrior is correct in a way. You have to pay it to someone. Just if you don't take Plusnet rental on top of the connection charge they are charging you £2.50pm more than they do if you have their rental, as well as that £50 setup, and there are no introductory cheap offers.
If you go back to the relevant website page
you will see it says "from £22.49 a month + line rental".
I recommend Pulse8broadband
for the line rental. (That link normally opens on the Business line tab, so click the Home one if it does). I used that for a while when on Plusnet broadband and still use it now on AAISP.
You could of course go the whole hog and take the P8 line and FTTC at £44pm inclusive. It is based on TalkTalk Business full LLU (MPF) and unless things have been sorted out may involve migrating on ADSL2+ then upgrading
