Weight? Both my Taipans are excellently balanced. This, for me, negates the weight of the rifle.
With my HST set to push 33.93 gr JSB at a clip of 51-53 FPE, I get 3, 10 round shots on reg (if memory serves me).
At first I thought, "this must be magic", with this size cylinder.
Another important feature for me was the easily adjustable power setting, with the HST accessible externally.
