We are going to be having the Rugby World Cup streaming from spark sport for customers in the bar through a Android Tv device connected to our audio/video setup.

The main concern I have is a consistent HD connection so there is no interruptions for those watching the games.

From talking to those at spark sport and some others, it has been recommended to have a 100down/100up connection for it to meet these requirements. 

We are currently with HD Net on 30/10 and asked about their 100/100 plan to which they recommended getting the CIR 100/100 from them which is significantly higher in price than just a standard 100/100 plan. Is it necessary to get this?

We have been looking at 2 Degrees 100/100 plan, however I don't know how good their business broadband is. 

The HD Net 100/100 plan is about double the price than 2 Degrees one. Provided the CIR recommendation is not necessary is there much difference between these two ISP's that it is worth sticking with HD Net?

Any suggestions would be greatly appreciated.

Cheers
