ive two pairs of e-vents (old and new style) anlong with a pair of invert avatsr's (see my display pic) there all basically the same mask except the avatars dont haave detachable ears and thus dont need a little tab to stop the ear rattling
as for lenses ive clear, smoked and mirror'd blue, clear ones are good all round except when its silly bright, outwith a low sun but ive the smoked for those days, more down to personnel preference
most half decent masks upwards near enough always come with a dual layer thermal lens, trickyest bit id say is finding an anti fog method that works for you
i use sprayable anti fog solution, some use anti fog gel even heard of some using rainex, motorbike lens spray or even johnsons no more tears shampoo, just a case of finding what works for you.
hope that helps
