Yeah maxpowers do yourself a favour and have a look at the Bell Super, went to LBS today to try on as well as Fox Flux.
Flux sat really high on my noggin and I wasn't all that impressed with the strap system, it kinda floats through a loop at the rear of the helmet so when you grab the strap on one side it pulls the left side through as well, not a big issue but im old and like to have things work efficiently all the time.
The Bell Super is just that, very impressive, it sits low on my head with great coverage. Dial wheel at rear is one handed operation, three vertical position at the rear for the adjuster as well. Strap system is simple, easy to use and does not float around when you grab one side.( when not wearing the helmet)
Size wise I measure up at 57cm, the Bell Medium sizing is 55cm to 59cm and it me fits perfectly with the adjustment wheel at the rear in the midrange position so I still have room to tweak it if needed. With the Fox Flux I struggled to get a good fit with any adjustment that I made.
With the IXS stuff when I did my research on those most folk said great lid but pretty much everyones report commented on how low the front of the lid sits on your face, obscuring vision when heading up a climb, that's what put me off the IXS.
Also folks reviews that have gone from the IXS to the Super rant and rave about the Super being a better unit.
So did I buy it too right !!!! Just have to get past my ankle reconstruction b4 heading out to try it.
Obviously everyones noggin and needs are a bit different, I am glad I took the trouble to try them on and suggest with what ever you buy try it hands on, your head is too important not to have the correct fit.
Hope this has been of help and just Google the Super, IXS etc and make your own judgements as to what will work for you.
