i agree with 14, but I think i'll pick 24 instead of 25. Historically 24 and 25 hits about the same, but lately, 25 hit once within last 15, but 24 has 0. so hm
also i'll keep an eye on 21, since most 20s should start to hit hopefully soon, 21 has been hitting quite well lately (3 hits in 10 draws!), historically it seems 21 will likely to hit around 1 in 6 or 7.
it seems to be hitting really high if u look at the 10 draws period, but if u look at 30, it's still below target (3 in 30). so I think 21 is still a good pick.
just my 2$cen+
