I do have the same problem, when I take lute back it seems so soft, such a low string tension... So since one month I started Uke I haven't played lute very much (and no videos... but I have to record some beautiful Da Crema recercari...)
This is a piece by Ernest Ka'ai, to present a beautiful instrument made by a friend of mine, amateur luthier (it is his own instrument, lent to me for the video)
