That's fair enough, I can assure you though Plusnet use a traffic management policy its only to prioritise other activities over others (streaming over p2p).
and Plusnet are known for good support and there online ticket system has always been rated well.
if you are to go with sky (as I'm sure you will get a better deal) and get a HG612 then you will need to lookup on getting it unlocked possibly and a MER compatible router to use with it..
I find the SR102 to be somewhat weak compare to others and the specs are not quite boasting fibre optic connections
(lack of gigabit Ethernet, 2.4ghz only and also only a max wireless rate of 144mbps which in most cases wouldn't be able to give more than around 40-50mbps, and that's in a good area where there's not too much congestion on the wifi channels)
I'm also a fan of Plusnet static IP service as they provide one at only a one off £5 charge.
Are you going for the upto 38 or 76 package with sky..... (Fibre / Fibre Pro)
