Spy goggles - Blizzard, soldier, orbit frame sizes?

Can anyone tell me how the Spy soldier and orbit goggles compare to the blizzard model in terms of frame size?? I bought a pair of blizzards from SAC and they feel just a little too small. I looked around for a local shop that stocks the soldier and/or orbit to see if those frames were a little bigger, but couldn't find any. I am hoping the soldier frames are just a bit bigger because it looks like there are pretty good deals for those out there. Thanks.

they seemed to be about the same size to me, all felt a little narrow for my head
