[Elecraft] K3/KX3 after market PTO knobs

[Linda and Bob]

Does anyone know if the after market metal PTO main and sub tuning knobs for 
the K3 or KX3 (main PTO) will damage or cause pre-mature wear and tear on 
the optical encoders? Any feed back on how the weighted metal PTO will 
improve the feel while tuning would be welcome. They are kind of expensive. 
Are they really worth the extra expense.

Please respond directly to my home e-mail address if possible, thanks.
