ROOSTER has been an online knickname from forever ago, mostly stemming out many many late nights playing navy seals on PSX -- had an awesome run a few times and someone said at one point "man you're like that song from Alice in chains....can't kill the rooster!!!" (HUGE dork level, I know....)
the 1050 came a few years back, it's the Engine from (what is now) my favorite motorcycle I've owned, TRIUMPH 1050 TRIPLE....it made logging easier to remember...
