Default Is anybody running a 4.30 on the 7.5?

Ive been doing alot of reading and riding in other peoples setup's and Im wondering if any of you guys are running a 4.30 in your 10 bolt. I know the risk of upgrading or just driving on the 10 bolt but Im considering throwing in a set on my 6 speed.

4.30s in a 7.5 is asking for failure. m6 + 4.30s definate failure. pinion is very small, not much tooth contact..... killed mine.
