The most sensitive effect of 10s I can think of is 11 v. A, i.e. hit when 10s are thin. EOR is about 4% in DD.
So, the question I pose to you.
Would you rather use an insurance 10 count for perfect insurance, and to solve the the sensitive 11v-ace issue, or fir that matter, 11 v 10 problem, or aces for 99v7 - and to round it out, 9's fir the monster 12v2 problem in monster counts also adjusting the insurance calculation for halves.
