I for one, believe Wladimir should be named Ring Mag Heavyweight Champ. My reasoning behind this is Vitali was named ring champ after his victory over Corrie Sanders for the vacant wbc belt. I believe Wlad is more established, and has a MUCH better resume then Vitali had. Vitali's claim to fame is a loss, and a win over kirk johnson and corrie sanders. Wladimir is the best heavyweight in the division, he defeated the #2 heavyweight in the world (Sam Peter), then defeated the longest reigning champion (Byrd), then Knocked out an undefeated top prospect in a voluntary defense, and then KO'd his mandatory.
The long short of it is, Wlad has accomplished a lot more than his elder brother, and his elder brother was named ring champ.
