I recently bought my first pair of Oakleys, the Holbrook XL, and I really like them so far. I've been looking for another pair, and saw a few titanium frames that looked good, specifically the Sutro TI and the Holbrook TI. I'm slightly leaning to the Holbrook TI since they come in prizm polarized while the Sutro only comes in Prizm. However, I've seen online that despite being titanium, many other frames that claim to be titanium snap easily and can't last years because of thin frames or the frames not being completely made of titanium. I was hoping someone here could give me their input on these specific models and if they're worth it or not.
