good, then today you learnt it is a terrible idea
it really is only good for one handed people.... I would say that like 70% of picking is tension, both with feedback and application.
If you are using a set tension, then you lose all feedback and only have a single strength of application, so you are basically picking at only like 30%.
not to mention just the time in setting it up is a waste too when you can just slip in a tension with your hand.
Unless you can come up with a good thing for the other hand to be doing, I still say this is a terrible idea....
