Dilemma : Beeman R7 or Weihrauch HW30 ?

I am trying to decide which rifle to buy. A Beeman R7 or it's near twin , the Weihrauch HW30 ? Weihrauch makes them both , but are there slight differences that make one better then the other ? Two of the major dealers in American list slight advantages in weight (5.5 to 6.2 pounds) and the ever constant war of velocity. Of course that battle could be resolved by what pellet is being shot out of which gun ? So which one to buy , and why ?
 
It would seem with all the learned opinions that the HW30S with the deluxe stock would be the best choice. AoA offers

one with a Weihrauck silencer , but the bundled scope is fixed at 4X. Not what I want. How could one go about machining the barrel so an after market silencer like the TKO could match ? Walther offers pre-machined threads on several of there rifles , such as the Terrus and the PCP Rotek RM8. Wouldn't it be nice if other air rifle manufactures followed suit.
