In the last QSO with Paul W9AC on 40m, he let me know of the Mercury paddle modified by KG2ED, which he has been satisfied with for years.
The lever arms seem to be shorter. Hence it causes less uncomfortable rebound feeling. In the e Ham net review, it has pretty good reputations.
Paul was not so happy with Begali models as with this paddle.
It could be a choice for me if I don't own the Bencher version of Mercury. If anyone is seeking Mercury, this Long Isaland one could be a candidate.
I have searched for this paddle and the maker KG2ED in the internet. But no info was available. Maybe, he has finished manufacturing his produce. Only used ones must be in the market.
