EBG should be manageable next year based on your flight pattern, but likely not Senator status if you are economy. I would stick to Eurobonus, even if you are flying another partner on long hauls. Just tray and avoid the 25% earning fares on LH. You are not likely to get op-ups on LH unless you are in a higher fare class, so I would stick to earning status and therefore choose SAS. As stated earlier, M&M charges high YQ and the miles are difficult to find a value. I have not had trouble finding Plus and Business awards on SAS.
