Change package or not . . .

[#1]

Hi
    I am currently on the plusnet Broadband Pay As You Go package
and regularly exceed my download limit (of 2Gb) but only by 2 or 3 Gb
each month. I have been considering switching to the Plusnet Unlimited
package but am worried about the traffic shaping for various forms
of traffic. The problem is, I cannot find any traffic shaping information
for the package I am currently on with which to make a comparison.
Does anyone know if these two packages have the same shaping? Is
the "performance" of Plusnet Unlimited worse than I am currently getting ?
TIA

Comparison can be found here http://www.kitz.co.uk/isp/plusnet_shaping2.htm
PAYG doesn't have any traffic management throttling. Might be worth looking a Pro, though depends on your type of usage.

Great, thanks. Maybe I'll stay put and just pay the extra as and when . . .
