other than the balsa options and the evergreen does anyone know any 90-100mm 100% silent walking baits? 

I just checked my box and the Spooks I have are silent.

While not a walking bait, the Deps 115 Silent Killer floating wake bait is a good option https://www.tacklewarehouse.com/Deps_Silent_Killer_Swimbait/descpage-DSKSS.html?from=basres

I have a number of Spooks in various sizes that are silent.  I also have a couple of store brands that are, too.  I don't throw many other walking baits even though I have tried others.

Yeah forgot about spooks.  I have literally thrown a spook 1 time in 20 years. Always go for other brands so I forgot they have silent ones. I'm surprised there aren't many others. 

Original Zara Spook model # 9255 has no rattles.
