Tube Size

I'm uncut and packing my 2-1/4" x 7" tube now, what size tube should I go to next? I use a 3-1/2" x 10" tube to pump my cock and balls.

Conventional wisdom is to go up in 1/4" increments, so 2.5"x9 would be my suggestion for cock pumping. For C+B pumping I personally have gone from 3x9 to 3.5x9 to 4x10, but mostly starting in 3.5x9 and only upsizing after 90 minutes or more.
