When I first joined these pages, this (OGS) and PS LBE were all 'the rage'....I got some early on to try and found that I felt the hype unjustified.
Oh, yeah, put some time on those coins or flakes and THEN you'll see, it was said.
Well, I've tried it again with time and it did become improved to my developing(?) palate and I kept a tin sealed for another go 'round some day.
Now, it's been about 2 yrs...that tin sits with a couple other VA forward blends....mellowing and awaiting special occasions.
I think some of us mistake the sharpness on the edges of fresher VA to be the 'spice' of Perique.
My experience with Escudo was that I fell in love with a fresh tin and when I smoked some that was at least a year in its sealed tin, it wasn't AS exciting.
I think the pipe I used initially for that first taste of the aged wasn't really a good match and subsequent bowls improved to my mind, but I don't think I'll ever get that same euphoria as my first time.
I recognize both of these to be well constructed and superb, but given the choice I'll go with Escudo.
To answer the OP's question, I'd say that either or both Perique to the OGS or Lat will yield added dimension.
VA's are much more difficult for me to 'master', and require proper cadence more than other blends.
