Without accounting for the the possibility of getting tossed, you are almost always better off arbing than letting one side ride. What is the Kelly % when there is a guaranteed profit? In the example above, the $90 wager has an EV of +$4.50. Unless you were giving up almost the entire 5% edge in the arb, the ability to essentially use your entire bankroll for the arb times the smaller edge will produce a much greater profit than $4.50.
What am I missing, if anything, that most seem to agree that it is better to only wager on the "supposed" +EV side?
