My quiver of choice in those kites would be 7.5, 10.5, Big Mama.
I would think the Smoke would fit in the slot you have.
If you do, it is only 1.5M bigger than your 7.5M, so they will overlap.
If you go Punch, it is only 1.5M from the Boss so they will overlap also.
Kind of close whichever way you go, but for surfing, it does make sense.
So, you gotta decide if you get more 9M days or 10.5M days and pick that size.
Your 12M almost stretches down to your 7.5M if you were only riding flat water.
I have 7,5/10,5/14,5 and used 7/9/12 last year
The Smoke and Mr Green are just magic, especially in waves. Maybe build a quiver around them depending on your wind/weight?
Jumps are OK but don't plane that much. Question of sending the kite earlier I guess
