Ok, so I think to myself, this is ridiculous... someone must sell some flat top jack stands.
Took a long time searching, and as I searched, I gathered from my reading that the reason for the V-shaped top is so that the load centers itself.
This is probably especially important in lower-quality stands, where an off-center load would be more likely to topple the stand or snap the top.
But, finally I found some. AC Hydraulic brand, jack stand nirvana... mmmmm....
Ain't cheap, though.

A little cheaper here, flat-top version not mentioned but they may carry them.

The AC Hydraulic jacks seem to get rave reviews as well, at a semi-reasonable price for what looks like very high quality and exceptionally low-profile clearance. Here's
one such review.
Aaaaahh.... no problem slippin' this beauty under a front spoiler:
I'm officially suffering from tool envy now!
