Since Vibroplex has keys for iambic operation in chrome, and other finishes, as well as single paddles, all of which are very similar to the Bencher line, I wonder how long the Bencher keys will continue? It seems that, although the Bencher line has been a good seller, Vibroplex could have made this move to eliminate the competition. I have several dual paddle keys as well as singles, and the difference between the Bencher and Vibroplex isn't all that dramatic, other than the looks. Of course the Benchers are a few bucks less, but, for me, the Vibroplex is a little smoother, and probably worth the little extra. However, since I bought the Begali, the others are rarely used any more. It is a fabulous paddle.
In the long run, it will be curious to see what happens.
