I have the Proto Switch EL's, JT Spectra's and Bolle T800's.
The Proto's are full face where as the JT's I have only ever used just the goggle portion but use them 90% of the time. I have yet to use the T800's as most fields don't allow them but I got them for a great price. I have used a pair of polycarb shooting glasses for one game in the past. They limited the potential for a BB's to enter but fogged up pretty bad.
