Stephen, I saw in the video you were wearing the strap across your body. I wear my strap on my right shoulder, with my camera going straight down. Is your strap better than others for that?
Also, on my Chrome biking/messenger bag, for the non padded area of the strap, the part that is adjustable, they use a seat belt material. Have you thought about using it for your straps?
Finally, about your website. It is using wordpress, which I think fits perfectly with your target market. It is not too full of eyecandy, like some flash based sites. It is simple and showcases your product well.
I will hopefully be able to order the Y-Strap, but I do not have a credit card, so I will have to get someone to buy it for me.
Thanks for making a good product, I would rather give my money to a small business, than say ThinkTank photo. I hope I will be able to get your strap!
