When ever I think what I sense/feel when I pull g's,the only sensation that comes to mind other the the tunnel vision when doing sustained pulls, is just physical exertion, can't say I ever remember wanting to look some where and not being able to because of g's.
My max has been 7.5 when fighting L39's I have about 15 hours of combat in both jets and props , and about 200 hours of pulling G's in aerobatics.
As I think back there is one place that is more difficult to look when pulling very hard , and that is straight up, I once made the mistake of tilting head back threw the bottom of a 6g loop, in a loop fight, had to wait for the unload to get my head back on my shoulders. You only make that mistake once.
