Well that wasn't really the point I was arguing.
Leg-spinners, Chinamen bowlers, doosra-bowling offies & left-arm seamers all offer an alternative from the fast/med right hand hegemony too.
But they all have to be accurate enough - wayward any of them is worse than "the fast/med right hand hegemony".
If you're accurate enough it doesn't matter what style you bowl; if you're not it doesn't, again - you're not good enough.
If you turn the ball enough or bowl a Doosra, you can bowl in the early 50mphs and below and bowl economically; if you're not, you can't.
& for anyone to attempt an answer (which is hard enough, as you've clearly weighted the dice, I assume "playing regularly on helpful pitches" excludes all sub-continent bowlers) you really need to clarify your criteria a bit:
a) What is "an acceptible number of runs"?;
b) What constitutes "the modern ODI era"?; &
c) What is "quicker through the air than convention"?
I've not "weighted the dice" at all - I've given you a type of bowler who I've noticed has almost never been effective and, upon you challenging that, I've tried to make you see what I've seen.
a) Less than 4-an-over, really - 4.2 is OK and 4.3 is - just - acceptible. Given that the time to bowl almost all spinners is the 15-40-over period and it doesn't make much sense to bowl them anywhere else.
b) Around about the 1992 period, really - it's not possible to give an exact threshold, but anything around the time of WC92 was the end of the era, and from then onwards 4-an-over is the threshold.
c) Almost all spinners bowl in the 50-1-2mph sort of bracket (some even slower). If you're bowling at 58-9-60mph, you're much quicker through the air than normal.
