All of them? Have you weighed what you have? I would wager that the total weight of screws in a Cinestar 8 is...oh...let’s say 500-600 grams (and that’s being generous). My cursory Google searches seem to indicate that Titanium is generally about 40% lighter than Stainless Steel. So you might gain 200 grams. And it’ll cost you a pretty penny. Seems there might be more efficient ways to gain back 200 grams.

John, are 30mm long enough? I don't se bigger ones. Do you have a chance to weight them? Well, 200g would be nice to save if the price is not too high.
No, the Cinestar uses 35 and 40mm for the long connections. I wasn't sure if this vendor has the ones we use or not. I was just saying that some vendors do seem to have some Titanium bolts at reasonable prices, so there is a possibility to search and find the ones we need at a reasonable price.
