In the bottom two pics I mostly wanted to show that Data's light has joined the big leagues of McGizmo and Mr. Bulk.
As far as weight differential between the Ti PD-S and the Spy 007, it's substantial. The Spy is far heavier. My Ti PD-S with cell but no clip/clip screws is about 95.29g. The Spy blew past my 100g scale - maybe we can get Dave to weigh one with cells installed - but I'd say it's a good 50% heavier. I'd guess at least 150g.
