Network was .030, and that was a lot. I had an Awesome Revs and Awesome Hook, disliked the Hook, and couldn't carry anything but light shots with the Revs. I think once you get past the high 20s, it isn't very driller friendly. Look at the Break core. If I remember correctly, its .024. That's strong enough to not make drilling it a hit or miss.
Just my humble opinion.
