are they comfy? i mean really comfy? i have a brand new Electra delivery 8, the seat i have is OK, but squeaks a lot......and hurts my "in between" area something fierce!! i saw a brooks saddle and fell in love with the look!! the cool front and rear springs were awesome. but they don't really seem too comfy for my daily 8 mile rides. so if they are worth it, which model is best for a cruiser bike that does daily 6-15 mile rides?
