Good choice Razma! And also a nice coincidence about your instructor being your old Sensei's brother.
You might want to keep your Shotokan training warm at home. Maybe visit some seminars in your area or train with a (former) co-student, maybe even your dad, every once in a while.

I know college can be quite the hassle on your training. I spent half a year studying abroad, which ment no training for me other than individual training.

Good luck, I hope you'll find a nice dojo again and enjoy your 'outing' in MMA.
