I have used the Bentley for over 18 months and can say that it works very well. The wand is lighter, one of its nice points, and as a consequence it might give some folks the impression that it won't stand up to heavy use, but it has. I have the new manifold and it works fine. Occasionally when I do have to adjust a jet angle its relatively easy. If there was an improvement to be made it would be to make the manifold less susceptible to going out of adjustment.
Even with that small fault I do prefer the Bentley to the Greenhorn which I have owned for around 4 years.
If you do get a Bentley you really should replace the
glide it comes with for a GreenGlide.
The disclaimer I have to state is that I have never used a
Prochem Titanium that is considered by many to be the best wand out there.
I'm looking forward to seeing the new
Sapphire that is rumored to be showing up at Connections.
