Don,
I've got a single shade, solar operated H.F. it's light, flips down easily
when I nod and works well with my wire machines.. I tend to leave it down
sometimes when grinding and the hot sparks sometimes darken it... I've used
it for several hours at a time and never had a problem with my eyes aching or
itching from exposure... I'd go for it...
I've also used the more expensive ones and I can't tell the difference other
than the adjustability... and they were heavier and make my neck hurt quicker
Santa is coming... have him bring along a new helmet for you... you've been a
good boy now haven't you ?
