How many rounds did you fire with the H2 before it became unreliable? Do you believe that the unreliability is attributed to wear/break-in on the buffer spring and BCG? To me it seems the more the gun has been fired, the more accepting it should be of a heavier buffer. Have you tried an ST-T2?
I have ~1500 rounds on my buffer spring and BCG and my BCM 14.5 mid still runs Brown Bear reliably with a ST-T2.

It's never been unreliable. Not one Malf. I don't consider failure to lock back with a buffer too heavy for the design a malf
But it just started cycling slower around a thousand rounds with the heavy buffer.
I would never let that thing near any of my guns.Have you tried an ST-T2?![]()
This changing around of buffers that seems to be popular of late strikes me as chasing down minutia for minutia's sake. It's one thing, I guess, to go to the range and change out the buffers a couple of times to see if there's any effect on the gun, but beyond that it just seems less than productive.
I have 770 rounds on one BCM 14.5" midlength with one failure to feed of Wolf 75 grain. I still have this gun and am adding it to my stable of loaners for guys that come out and shoot with us. After that failure to extract I went to Brown Bear 62 grain (still a non-recommended ammo) and did not have another failure in 695 rounds (without cleaning).
I have 443 rounds on another with 3 failures to extract (also with suspect ammo). This was a gun for an article and has since gone back to BCM. All of this was on H buffers. If I had to shoot that ammo in these guns, and continued to get failures, I might play with the buffer weights. But Paul was pretty clear with me when he sent me these guns that they should be used with higher pressure ammo and I ignored that at my own peril. Chasing minutia myself, now that I reflect on it and look back at my logs.

It was the ONLY buffer that did not work consistently in my 14.5 with pmc, brown bear, ae, and aguila; 55 to 62gr. I wouldnt waste my time with it.
(And by didnt work, i specifically meant FTFeed)

I'll have to rerun another full auto test with the rifle buffer system and M855 again to see if there's any noticeable rate of fire difference from the original video.
