Good luck to you mate, if the jacket gives you more confidence then wear it with pride. But as has been said, don't let it be your sole form of defence, learn to ride confidently, take training if you think you'll benefit from it, and above all enjoy it.
Absolutely. I've taken some flak for getting carried away with safety equipment because people assume that i'm skimping on training. However, I figure that training my mind/body as much as possible and then adding on as much technology/safety hardware is the way to go, it's not one or the other.
