So I'll be getting my brevet feet wet this season and i'm not ready to commit to hub generators. i've been looking at the ixon lights at Peter White, which sound much better than the cateye el-530s, but are more than double the price. since i don't think i'll be doing anything over 400k this season (i.e. not a lot of night/early am riding) what advice do people have for lights? I really enjoy distance, and hope to make randoneuring a big part of my life, but if it doesn't work out i'm hesitant to make the big commitment to the "real" lighting systems just yet.
