As a purely safety issue I'd be more inclined to make it as easy as possible for the starting line crew, as well as your own crew, to visually make sure YOU are strapped in and got your brain bucket strapped on. All that safety gear only has to work once and the first time you space out hookin' and pullin' you'll need it to work as designed. We've ALL forgotten at least once to buckle up, pull 'em tight or even strap that helmet on after shoving it on your brain cavity.
