I wouldn't give up EV on your insurance bet, personally. That's a 100% play. Not splitting tens, not doubling 8 or 9 or soft vs. big upcards, hitting 12 and 13 vs. big upcards, and standing on 15-16 vs. small upcards are better cover.
Also, if you have late surrender, this is worth WAY more, and gives you a lot more room for cover.
