I had red somewhere (maybe in Fatman´s book) that they provide (usually) greater resistance and don´t wore out as quickly as cheap rubbert tubes, for example.
Is that true in most cases? ... I suppose it would depend on quality (so assume it is same prize range of steel and rubber expander).
Do have steel type expanders another benefits over tubing - if so, what pros?
I could think of only cons (steel "tubies" can´t bend as rubber, workouts are more noisier, more possible damage with snaping tube, etc...).
Do anyone here work out with steel expander more than with tubing?
If so, why?
