I also had that first gen release of the FMJ/Fire OTT without the pads. The provided stick-on pads were pretty odd round dots of foam, and ended up leaving odd marks on your forehead. When the next gen came out with the inserts, I reached out to Oakley and they sent me a set of the foam inserts which I installed on my OTT. Since the OTT didn't have the cutouts in the frame for the pads, and the fact that the pads were larger and more formed for the frame - I found that it created a much more comfortable fit. I liked that fit much more than the gen 2 inset foam, since it was both comfy and give a few mm more clearance from my forehead, eyebrows, etc.
