One of the forums sometime ago asked the same question, after some research I think they came up with the blanks being G-200.

Josh would appreciate your opinion on this the WS86MC blank color is green not blue as the 200's are? The guys at WS said the Lamiglas rep said it was made on a certified pro blank.

Yes we use the same material in the wholesale sports house rods as we do in the Certified Pro line. The major differences are the guides are not the same as the certified pro line and some of the actions are unique to the wholesale sports house rods. Also the wholesale sports house rods only come with a one year warranty as the certified pro line comes with a lifetime warranty through the manufacture. Hope this helps.
