LOL!
Understood and fair.
However, circumstances at home conspired against me and the shave has just been completed (15 mins ago).
I would like to point out also, that I did not use a new blade, but instead decided to run with the Shark Super Stainless that gave a great third shave on Tuesday.
Not the best time to experiment with a first ever forth shave with a blade maybe......
This circumstance also made me, in the moment, decide I was just going to do the WTG pass with the new Rocca head.
Definitely could tell on the XTG and ATG passes in the Tech, that the blade was “off the boil” but it was an acceptable result, although for the cost of a blade, I won’t do it again, no point.
@Dr Watson, see how I am hanging it out James, building your anticipation........
Rocca head - fit and aligned much better visually. I have always found this a very fussy, unforgiving razor, probably a bit too aggressive for me, but also useful to exaggerate blade preference.
I didn’t hold out a great deal of hope for much change this time, also as I ended up with an extra day or two growth (usually 2-3 days).
Much improved!
Mowed through the extra length stubble easily, still more blade feel than I prefer, but no nicks or irritation, no skipping or tugging, just a sense that the blade doesn’t have the edge I am used to or expect.
I switched to the Tech and felt the lack of decent edge a little more.
Will do a 3 pass shave with the Rocca only and a new blade on the next run, but dipping my toe in cautiously this time was a pleasant surprise and a clear and obvious change of behaviour, that was unexpected.
At this time very happy but will follow this up Monday or Tuesday with a proper test.........I hope you can survive that long James.
Will also get around to taking some further photos for reference and info of others.

I too found the skipping/tugging has completely vanished with the replacement head.
