Hirobo Stream-50

It was a very pleasant surprise when I found out that it was supplied with 
the soft mount and retracts. I was originally going to install a Saito 72 
that I all ready have. But after finding out about how nice it has been done 
I think it deserves a YS63. I am interested in seeing the pictures. Thank 
you for the advice.
