Don't know if this'll make sense but it ain't that I haven't tried (3x ) here to obtain a better understanding of what the 'old' vs. 'new' version's visible differences are.
Might it just be that the hole in the middle of the atty surface is larger now (perhaps making it appear even more like a washer)? I've read some other threads including older ones where a 'washer' in the 901 was referred to (only incidentally, not as the point) as if it's just a normal part of the design. I finally did manage to see a pic of a current 'washer-included' 901, and compared it to a few other SLBs I purchased months ago, and the only real diff I could see was that the center hole appeared to be slightly larger on the more recent one...
(Which I think I can now conclude are in fact the same ones I recently bought myself from HC. Btw, no questions or complaints on HC's subforum about them [have seen some post-order-receipt compliments in same time frame]... and many ppl buying there are doing so in bulk, so if dissatisfaction and a considerable performance diff were widely perceived I'd kinda expect to hear it there...)
Is it at all possible that the fear of 'washers' has just spread to the 901 from the original issue with some 510 atties bearing a design that's closer to a 901 (including in resistance), which some don't like; but that the washer-like design really is normal for 901s?
