I only get about 3.5K miles to each set, and that adds up in a hurry.
Most of the time the major difference between an H and V version of the same tire, is initial tread depth.
The V will have less tread depth in order to somewhat eliminate the tire squirm that causes the heat that causes the tire to fail the "V" test.
Given this, I'd expect the H tire to be heavier, as it has more rubber.
H is, in fact the better buy, as no Airhead needs a V tire.
It's pretty academic in any event.
