Thanks to all for your feedback.
I used Gosen extensively in the past and I found that it loses tension rapidly and within a few hours of play you have uneven response from the string bed. This happened to me even when using Gosen as a cross. On the other hand they last fairly long. I have not tried Forten, but some comments seem to suggest is fairly similar to Gosen, with maybe a softer, less lively feel..
I may try the Prince original, even if it seems to have a fairly stiff rating.
