I am in pretty much the same boat - I'm looking to finish the year around 105,000-110,000 MQMs. For the moment, I've decided NOT to pursue DM and will rollover a significant amount of mileage. I'm not sure how much I'll travel next year, so if I go into 2016 with the rollover what I have now, I'll easily hit GM next year and likely PM again for 2016. I'm not sure spending the $$$ for 15,000-20,000 MQMs worth of mileage runs is worth it. However, if some work trips pop up between now and the end of the year that get me to within 10,000 MQMs of DM, I've decided I will likely MR and push myself over the hump.
