Cheek Pads - Tac Ops vs Blackhawk IVS?

[glug]

I'm trying to decide on a cheek rest for my sps varmint. I sort of have it narrowed down to these two. Anyone have opinions which is better?

Tac Ops: http://www.tacticalworks.com/Tactical-Operations-Ammo-Cheek-Pad.html
Blackhawk IVS: http://www.blackhawk.com/product/IVS-Performance-Cheek-Pad,608,1406.htm

I know there is also an eagle industries one, but as far as I can tell it's identical to the Tac Ops minus a couple of ammo loops.

I know some Blackhawk cheek pads are not impressive but this IVS one seems to have really good reviews and is a good deal right now:

I guess the biggest question for me is how the IVS "compression-molded technology" compares to the soft suede padding on the Tac Ops. Anyone tried both? Off hand I'd guess the suede is overall more comfortable but maybe the IVS would be nice for shooting longer stints in hot weather.

Of course all other things being equal the Tac Ops is made in the USA so that's a nice to have, albeit a bit pricier.

I should add-- right now I can get the Blackhawk IVS for $27 and free shipping, whereas the best deal I could find on the Tac Ops is $35-40 plus another $5-10 for shipping, making it about $20 more expensive overall.
