Sorry Ben, it's another "I went shopping" post, and this one wasn't even successful. After Lozzo's post about F317s being 80 notes in J&S I thought I'd give one a try but it just didn't feel right. The helmet seemed perched on my head even though I'd gone up to a Large and currently have a medium[1]. Worst of all was the ridge across the back of the neck from a seam in the lining. I tried the non-flip N800 also and that had the same seam in the lining. Shame because it was the right price and had the features I wanted. I tried a nonflip Shark which felt much more comfortable and a better 'fit'. But this didn't have a removable lining and was reduced to 100UKP because they were in gash colours that they couldn't shift. Guess I'd better wait until the piggy bank is a bit fatter and try again.
