I had this same question. I read the description, and was thinking about trying them, but after looking into it I ordered the Infinito set instead - an even pricier option, but here's why.
After SBM, I looked at Dogal's site, to find that they are currently on holiday. I then looked up Giacomo Parimbelli, who is credited with developing the Infinito set. My Italian reading skills are not that great, and google translate leaves a bit to be desired, but between the two, I became intrigued by two things: firstly, on the Dogal website, the description states that the 4th string in the set belongs to the treble grouping, not the bass. The 5th string is a 'doorway' to the full-bass 6th string.
Secondly, I looked up an interview with Parimbelli, who says that often guitar strings are developed with volume as a consideration, whereas he believes that the beauty of the sound is more important than the volume of it, and that a perfectly pitched note should not require volume in order to be heard properly. Dogal offered him the opportunity to do this. (Patches of this are my loose, cross-referenced translation.)
At that, I was ready to say, 'Shut up and take my money!'
I ordered a set of soft tension Infinito yesterday from SBM; the Maestrale will have to wait.
I have a fortnight to wait myself -I am in Scotland.
