would or could I see a difference with a different plan ? If so which plan thank you

Hi Mark,
Kenneth does make a couple good points, Bolt speed is no longer offered so if you changed you wouldn't be able to go back.  Also depending what you are using it for the Lightning 50 isn't usually required.  More specifics on the plans and what they offer are available at http://www.mts.ca/mts/personal/internet.  One trouble you may have with the Bolt plan is the 32 Meg connection you get is shared between your internet and TV service, so the more you have going on with your TV, the slower your internet will be.  This is the exact same for the Lightning 50 plan.  The Lightning 25 is a dedicated connection so the speed would be more consistent.  To upgrade or not to upgrade in your case could be dependent on what you specifically need the speed for (download or upload) and how much you use your TV service.
