No problem, and don't forget your helmet, some DEC guys will write you a ticket if you don't have it. I use mine because usually it's so cold that I really need it to keep warm, but as far as it being necessary, that is debateable, and there are many opinions on the subject.
Good luck.
ps most of the info. that I know was posted on this site a few years ago, so maybe a search will bring you some more results, there have been many discussions here on the subject!!
