The wifey wanted to do the same last rear around the alps and Austria


. We took a hand held video camera and my kodak Digi v610 which has video capability. The results were very different. The best footage was from the Kodak, the picture was clearer and more stable whilst the video recorder was jumpy(I did put stability control thingy on, but every time ewe turn the vid off ewe have to select it again

which was fiddley with gloves on). We think the kodak was easier to manage and lighter to hold whilst on the move, as wifey needs to hang on don't forget


. (braking heavy into hairpins and giving it a handful coming out etc)
If you go for the helmet/fixed camera option, ewe may get a better set up, but ewe may loose the views of the landscape and scenery that will be to the left or the right and plus the wifey will have nowt to do. Plus at the end of the trip it will be all her own work and let me tell ewe, that fact alone will get her to get yer mates to watch the Video
Edit- my kodak took SD cards. Next time I am going to take dedicated video and photo SD cards. As a 2Gig card takes one hour of footage alone, so it will be easier to edit the footage on your return.
