Positive vs. Negative Power Shut Off

[Wbulk]

I am getting close to putting my body on for the last time and am debating about putting in a power shut off switch. This is the time to do it. Anyway, I have read some threads on the subject that addressed types of switches and locations, but none really got in to the issue of putting it on the positive vs. negative side. I have read over on the FFR forum where a few guys changed over to the negative side to solve some issues for them.

I am thinking of putting it behind the passenger seat for easy access. Since my battery is in the trunk I can easily run the ground wire to it and then bolt the ground wire off the switch to the frame on an unused roll bar pad mount. It would seem that the ground wire switch would be the more logical and would avoid all the other issues with the positive set up. Am I missing something?
