Looks like he is loving the Lantus...love those long blue surfs. Not sure I would but if you want to try to bring his overall curve down just a touch you might try a fat .5u I don't think you want to add much but he is still in triple digits at nadir most days if you fatten the dose up just a tad, he might drop down nicely into the greens without going too low on ya.
