I had been with XTRA for the past 5 odd years but was sick of the fair use policy they ran with the GO LARGE plan, I never really used much bandwidth on the plan yet my connection was pathetic to say the least at peak times.
I'm glad to say I've experienced an instant improvement in speed and stability. Youtube videos are streaming perfectly my online poker program hasn't cut out and I'm able to run both computers without one dropping off.
Although I was always expecting a better connection Xtra had made me think it was my computer or my computer programs which were causing the bad connection they told me Youtube had so many people watching their videos I wouldn't be able to have them stream at peak hours. What a load of bull, makes me glad I made the change and also It is going to work out cheaper.
So If your are stuck on the Go Large plan, do what I did - use your get out of jail card and switch to Xnet.
P.s(Thanks Nate my n00bie writing skillz not so great)
