Basic word of advice: If it complies with all of the bumper rules, it probably is legal. If it doesn't comply with one or more, it is not legal. If you aren't sure, you're probably best off asking Q&A about it before you get to your first event; that way the inspectors aren't either telling you to change it or asking the GDC and then telling you to change it.

I do remember hearing about some weight-transferring bumpers back before the standard bumper design came out (2006); those were effectively banned by the bumper rules in 2008 (standard bumpers were optional in 2006 and 2007).
