Had a Graham 2.2 for years. Same design, same silicone well deal. All that changes is viscosity. All you are getting for the inflated markup is someone else's idea of what sounds best. Which is fine if you hear it and agree. Otherwise, for what it costs you could probably get 2 very different viscosities which by mixing you could have a dozen or as many as you want to try. Once you have a syringe or two and some Q-tips changing fluid is trivially easy. I just can't think of a single reason, outside of sheer laziness, to wait and pay. If it makes you feel better when you get the formula you like you could always write Emailist Engineering Topaz Blue Silicone Damping Fluid and stick it on there.
