I agree with paulhenry, in that the best look is the one that you like. I also agree that in an 8yd 16oz tank, a knife pleat seems to be a very good solid choice.

I will offer one suggestion regarding the type of pleating (sett vs. stripe). I personally like the look of pleats to the stripe. However, when I purchased my first and only tank, I took the advise of my kiltmaker, and agreed to have it pleated to the sett. Why??? Because my chosen tartan (the one in my avatar) has a thin red stripe, and many tartans pleated to the stripe are to a white (or at least light) stripe. We were not sure if the red stripe would show well, and didn't want to take the risk.

Your chosen tartan has a pair of thin white stripes. I imagine that you could select one or the other to center on the pleats, and that might look very good. Or you could just go with pleating to the sett. Decisions can be so difficult! Whatever you decide, I'm sure you'll be happy. I know I am, although I keep telling myself that I will have a second kilt in my lifetime, and it will be pleated to the stripe.
