Have a look at the ESAB G50 full air fed setup with the PAPR unit. Has the clear grinding visor, with a flip up auto cartridge. Also has the clips for a diopter lens. Price is very reasonable too compared to the 'higher' quality makes.
Never used this but did consider buying once. Looked a bit front heavy to me but you never know till you try. Yeah carbon filters good for farts worked at a place where the in joke was to fart in each other's blowers. One guys **** was so bad he made a bloke sick in his helmet -- he didn't stop till the end of the weld thoughHave the g40version of this, exactly the same just a passive lense rather than reactive, and can vouch for it being a decent bit of kit. Small and lighter than a lot of others, especially the speedglass lids, can fit a cheater in it easy, can even wear glasses in it easily enough if you want.
Get some of the carbon filters for the blower though, especially if youre partial to a bit of spicy grub
