The rapid ascent rates present in freediving could cause ingassed nitrogen to come out of solution.

Thanks! I think Ill keep them seperate for now! but still very curious do you think if i was conservative with both say a shore dive to 6-8 metres for an hour and maybe large surface intervals freediving say 5min survace to 1.5min dive and keep it under 10metres?? sorry just dont want t miss out if i dont have to. cheers

I'm very curious about the details of the mechanism behind DCS in free divers. So I spent a good couple of hours furiously searching for articles and papers on the subject last night. I didn't come up with much. It seems to me that there hasn't been very much research done on the subject -- well, at least not in comparison with the amount that's been done on DCS in scuba divers. So you might find that no-one can give you an authoritative answer to your question. I hope I'm wrong, though -- I'd love to know too.

From the material already linked to in this thread, I'd be surprised if a couple of free dives before flying would be a problem.
My understanding of those cites is that the trouble with free diving after scuba is that it affects your SI off-gassing rather than giving you significant new nitrogen loading. Unless you do multiple repetitive deep free dives, which was the situation for the Taravana divers.

I thought the real dangers when free diving after scuba were
a) venous gas emboli formed after scuba diving could be re-compressed, pass through the lung capillaries and end up on the arterial side where they would re-grow during ascent and cause all kinds of problems
b) some free gas would return to solution and due to the rapid nature of ascents with free-diving, could come back out of solution in much larger bubbles
