Considering the ranges listed, and the fact that you're shooting paper, heavy bullets aren't really a requirement. With that as reference, I'd suggest the slower twist... and perhaps even slower than 1:9.

Back before the military desire for heavy bullet 5.56 loads, the typical .22 cal centerfire target/varmint rifle had a 1:12 ~ 1:14 twist... with the typical 50-55 grain FB or BTHP doing quite nicely in a relatively slow 1:14.

If you get a chance, go to the Berger Bullets website and take a look at the recommended twist rates for their various bullets in the varmint and target selections. Figure out the heaviest bullet you'll ever want to use and go from there.

I wouldn't worry about wearing out a barrel... more barrels are ruined with poor cleaning methods than with bullets.
In a non-competition setting you'll get several thousand shots through a barrel before it might start to push your personal accuracy drop-off button.

Cheers,
C
