Ti is definitely more brittle then steel. But I believe you can find higher quality fasteners then the OEM ones. However, no matter which ones you use, a high quality driver in perfect shape will help. I also pretap the threads as recommended by 3 Racing's Diff. Building bulletin.
Either way a striped or broken off head will ruin you whole day and possibly your diff.
