By way of follow up, I completed my week's shaving routine this morning as planned:
First Pass WTG with .68 JAWS
Second Pass XTG with .68 SB
Observations:
1) Improvement noted in neck area versus using .68 SB both passes or .84 SB both passes
2) I learned that a small section on one side of my neck requires a diagonal stroke to achieve bbs most efficiently. Very good to know and it makes the trial period worthwhile since I hadn't observed this before.
3) I must admit that I did introduce some minor irritation post shave since introducing the .68 JAWS to my daily routine. To me, this makes this setup a special occasion shave for me, only, if I am coming off of one day's beard growth.
4) Anxious to try the JAWS after a weekend's beard growth, which was my original reason for ordering.
As always, YMMV...
May I ask what your daily driver or razor rotation is outside the new Gamechangers? I had my eye on the .68OC or JAWS but your reports of some irritation is concerning. I am still searching for that panacea of mild/smooth but efficient.
