REFLECTOR: DH engine vs. Velocity Beauty

[wooden at alltel.net]

I have ordered the DH and just got off the phone with their office.  They originally indicated that my inverted engine would be delivered in February, but now they have put off the delivery date until May at the earliest.  I believe it is the best engine for the Velocity, and I am willing to wait until they get it right.
