I have tried Dogal venetian strings recently. Currently I have Venetian basses paired with Mari 100p - a very nice match.
I did spend some happy time with Venetian trebles, too - they are similar to the Diamante trebles, but if anything more 'bubbly' (can't think of a better adjective). They are full sounding to me, and the basses are quite 'throaty'. My Michael Ritchie is oil finished, and seems to like their fatter, jazz lounge tones.
