I have a Schuberth and it's a nice lid.....a bit noisy...but very comfy....better than the x-lite flip i had before.
If I'm just nipping out on a local run or looning about i wear my Roof boxer.....its just so much...er, easier......not as comfy by far, in fact if wear it for more than three hours at a time it gets quite painfull.....so the Concept wins on the long runs.
The Schuberth won't take Autocom speakers without a bt of cutting about.....the speaker holes are there, but not quite big enough.......
The visor isn't great in that it just won't stay open properly for me....so its a bitch in very cold/rainy weather at speed......but otherwise it's very good, and i do like the sunvisor shield, even if it is a bit fiddly to find the lever sometimes.
I'm not taking it to Land's end or on the E.European trip though......I'm wearing my Tour-x for that.....apart from the d-ring fastening (grrrrrrr!!) it's even better than the concept.....though I must admit I haven't yet poked around inside to see what the Autocom fitting's going to be like.
Haven't tried the system 4....though I believe it's made by Schuberth as well so apart from the price, I don't think there are too many differences.
