I have a Konami HYPERSTICK and I use it for PS Raiden DX and PS Strikers 1945, and it suits me well (it could be a little more tighter, but its ok, its a little loose, thats all)

this website says that this stick uses "full Seimitsu, like some Sega Virtua Sticks". is that true? does this stick uses Seimitsu parts? I dont know, I didnt open it and wouldn't know even if I did open it, unless there is a "made by Seimitsu" on every part inside it...
1 question on this part; is there a difference between different Seimitsu parts in terms of tightness/looseness of directional stick? if I buy a stick with Seimitsu parts, will directional stick be always of certain tightness or there can be a significant difference between different parts of Seimitsu directional stick?
I need to buy some sticks for SFC and SS, so I was thinking about HORI HSJ-12 for SFC and HORI HSS-07 or SEGA HSS-0136 for SS.
so, my questions would be:
does anybody here know what parts these sticks use? do SEGA HSS-0136 use Seimitsu parts and what version of it, if not all?
is there more than 1 version of this stick?

and if there are more than 1 version of this stick, how do I know which one is which and what parts do they use if they use different parts for different versions?
and what parts does HORI HSJ-12 for SFC use?
I intend to play these games with it: Assault Suits Valken, KiKi KaiKai Nazo no Kuro Mantle, Wild Guns

and what parts HORI HSS-07 for SS use?
I intend to play these games with it: Tenchi o Kurau II, Batsugun, Metal Slug, Sengoku Ace Episode II, Cotton 2

Im asking all these questions, because, although sticks themselves are not that expensive, sticks + shipping are, so It would be nice If I knew what sticks would suit me, so I can buy them
Again, thanks for all information U can supply me with, its much appreciated!
