Wouldn't S145 be a 145 height version of S130? Also, if it were free spinning, it would be Eternal, so it would be Eternal Defense.
I just finished designing a quick 1 hour Sand Sphinx MD145 (Metal Defense) MF (Metal Flat). Because we all want to see a Metal Flat part in MFB. Problem is, it's in my DSi's Flipnote Studio, so I'll have to figure something out.
EDIT: Here it is!
The face depicts a sphinx of sorts although I'm questioning if I should have just put Tut's face.
It has five sphinx heads on it, with bricks and stuff for texture. Not quite as heavy as Pegasis II or Aquario, but it's pretty great.
Sand is like Dark with wider 'fangs'. There are five fangs and pill-shaped things on it.
I SWEAR IT WASN'T STOLEN
It was based off of a hybrid of ED145 and S130, but with metal around the edges.
Metal Flat is a flat tip and metal sharp combination. It's somewhat original.
The description is nowhere near up to par with BeyWiki articles, (or, in fact, any descriptions made in entries preceding this) but it seems to work.
