1. Pro-Tec is a great company. They are different because their helmets are better and more comfy.
2. I hate gear that is uncomfortable and hot.
3. I put stickers on my helmet if that counts. Other than that, no.
4. The only trend right now really is bucket helmets with visors. Looks pretty good.
5. Comfier, slimmer, elbow and knee pads, and cooler, more ventilated helmets.
