I've got a Vforce Morph, same lense as the profiler, has changeable peaks like the profiler, has a pull down neck protector that the profiler doesnt, and in my opinion, looks nicer. Its half the price too.
I've worn flex 8s for over 5 hours of reballing and was sweating like a *insert joke* the entire time and they never steamed up, now have set them up as proflexs and they are more comfy, especialy on the ears and have much better ventilation.
Never had a problem personally with spectra lens goggles
Since used profilers which i have had some dramas with but only in serious conditions and i have now just moved onto Events...........will let you know about these after sunday!
