Having best drop weight as backup is always an option .Once you go electronic, it is hard to go back to a drop weight or crank. My Wise has been in use for 5 years strung a bunch of rackets, and it has performed without failure.
If you do any volume of stringing, the Wise makes it so much easier and faster to set tensions, and you eliminate the constant raising and lower of the bar. It is just as accurate as the drop weight and saved me about 10 minutes per racket. Not sure I could go back.
Very nice implementation of the Stringway / Wise.
You`ll never know when something can go wrong with electronics like Wise sor lifting weight will be your only option.
