the eg1 are decent goggles and, unless you have a particular reason, don't see the need for a "upgrade". Fisbowls are stupidly gigantic and Von Zipper quality is no higher than Electric. Oakley have a slightly higher lens quality and build, but the exponentially high price doesn't make up for it, imo. If you've got money to burn, you could go photochromic, but these lenses supposedly don't as well in extremely flat llght as the standard cheaper yellow lenses.
I've tried the interchangeable lens route and, although they're not difficult to swap, it is a relatively time consuming process. The more seasoned snowboarder frequently ends up with two sets of medium-lower end goggles, each with a different lens. When the light goes flat, just walk to the car and grab the other goggles...no time wasted fumbling with lens exchange.
I've got two sets of Dragon Rogue that cost me under $50 a piece (bought off-season)
