Sher-Wood S77 Composite shaft

[Nosferatu 8]

Hi all , I've recently bought the aforementioned shaft in a special offer but can't find any info on the thing other than the 90 flex as stated on it . Is it a European rebranding of a US/Canadian line or a rename of an old TPS model ? There seems to be a fair few German and Eastern European shops selling them but haven't seen it on US sites. Anyone else have one or have an opinion on it ? Seemed decent enough when I used it at last hockey session , would be nice to know what it is comparable to .
