Thanks for testing and posting, Mike (miksatix)
You appear to be listing three moderators. If that is correct, you are showing two that appear cylindrical. If there is a third, is it the Huben pistol oval that the 2 x 6.5 was derived from?

Well, Mike, you did provide info about the latest 2 x 6.5, so thanks for that.
The reason for asking about the 1.5 x 6.5" oval offset Huben pistol moderator as a comparator is two-fold:
It works really well.
The 2 x 6.5 coaxial was derived from it.
So, if the 2 x 6.5 works as well as its oval parent, then people shooting at 50+ FPE should be happy.

Are these for sale!!? .30 and 35 cal, 1/2 unf and m18 thread respectively...MikeAllen,
Mackeral5 on this forum has quite an impressive collection of airgun moderators, including the STO Sarissa. He told me that his Sarrisa works very well. That it works better at higher power. That it makes PCPs with a stock shroud work better than other moderators of equivalent dimensions. So, based on this endorsement, getting a Sarrisa would not be a mistake. That said, I suggest you ask Mackeral5 to speak for himself.
Now, Mackeral5 also has a number of custom mufflers and inserts that I designed for him. Some work better than others; which brings me to a side-note: The usefulness of factory-made moderators as benchmarks. So, when you have your Sarrisa in hand, I would like you to compare one of my custom mufflers against it. I do not expect my 6.5 x 2" OD effort to match the Sarrisa, but to give it a run for its money, at a quarter of the price.
To facilitate such a comparison a .25 cal 6.5 x 2" muffler with a half 20 thread will be on its way to your shipping address, by the time you read this, free of charge. The only costs you are expected to incur are for your pellets and air.
This cylindrical muffler was derived from the oval offset moderator I designed for the Huben pistol, shooting at over 60 FPE. And, it works very well in that application. The wall thickness is heaviest around the blast chamber; then steps down as the pressure drops towards the front, to keep the weight down.
Anyway, I would not dare suggest that you try my offering first, to see if it meets your needs, before your decide on the Sarrisa. I would rather you rank the two mufflers, taking into account the absolute performance, size, weight and cost. Then post your impressions or results on open forum.
I shall close my topic deviation with; I trust that your Sarrisa will live up to its reputation.
Note that the waffle pattern ribs were added to the OD of the smooth muffler version that is shown in section below:
