The standard specs between titleist and miz are quite different, a 2* upright miz plays only 1/2 a degree more upright than a titleist standard. The head shape design is also a bit different, titleist generally has a boxier look to them, meaning the heel and toe are closer and the face a little deeper, while miz is stretched a bit longer between heel and toe and a little shallower. Its minuscule millimeters but it does change the aesthetics at address. Your specs are probably fine, you might just need a little longer to get to know them. Have an instructor or fitter look to see if you are making a counter move to the longer lengtg - ift may take time to adjust to the new length and if you are "trying to make room" and falling back on your heels that will get the toe strikes going.

Maybe you were badly fit for the MBs and have learned compensations that are revealing themselves in the new clubs? Or, you were just "over fit" for the new clubs, meaning the fitter got a little over zealous with making a set with custom specs that you maybe didn't really need.

Most people can play standard length clubs. There isn't much advantage to lengthening clubs unless you're really tall with short arms and you feel uncomfortable hitting your wedges. Otherwise, you're probably doing more harm than good.
