I've shaved on 5 consecutive days with the Tech, using the same Sharp Durablade.
It's getting easier as I log more shaves, clearly. I had an earlier round with the Tech that was a bit rougher, even though the performance was incredibly efficient. Now, the consistent application of a feather-like touch with a steep angle (except for light buffing where I use a bit more of a shallow angle) provides what feels very comfortable, with the occasional exception of the ATG/XTG on the chin. I wouldn't call that part uncomfortable, but perhaps there's just more resistance. Doing a little extra up-front work on the WTG pass helps considerably with the subsequent pass(es) on both the chin and upper lip, however.
This is clearly a new level of BBS, akin to the R41 but a different face-feel (hard to describe, but I think MJClark comes closest in an earlier post). The Durablade - often maligned in forums, but so far a great performer for me in every razor I've tried - has now weathered five solid shaves, and the decrease in efficiency was apparent today, but it didn't feel any less comfortable. I might go one more round with it and then retire it, unless there is an unforeseen dramatic comeback!
I'll probably switch back to the R41/Spitfire combo next week for a better comparison. Using the Tech has made me a stronger shaver - now we'll see what happens with the other beast in the ring.
