Hi All, Just looking for some advice from the experienced user base here. I am about to buy all my gear with my bike and I am pretty set on my choice of helmet. Looking at the Shark Speed-R S2 and I want to know what bluetooth kit I should look at and their compatibility with the Shark helmet? Specifically looking at brands other than the sharktooth kit - I may go this path but possibly not. I do like the new release coming from Interphone (Urban) but not sure I want to wait. Thanks in advance guys.
