Ha Ha this thread is gold.

There is zero change in frame geometry or reach to the hoods, or drops. The tops are moved back a bit to accommodate more surface area to rest your forearms. The width is narrower along the top to accommodate natural position of your forearms in that position while still giving you something to grab with your fingers (hoods). The drops are flared to accommodate the preferred bar width.

I wouldn't mind trying them out. The only time I ride the tops is if I am resting. Riding the tops is not a power position, think about it.
