Azhar- Dago eh? Nice choice
I am going to say 10x8 or if you have time shave down a 10x8 into a 9.5x8 APC- You may get away with a 9x9...
That YS is going to be AWESOME! Ceramic piston? Sounds killer to me- other than a Jett-50/60 the YS is the strongest sport alternative!
Keep us posted and get some pics loaded will ya?
