@FirebarUK not even close to being an expert but I also dont like cartoony edge highlights. I tend to just use a shade lighter as a thin one and don't do the whole model unless I think it's actually noticeable.
That said, depending on the shape of the thing you are doing can be a variable if thick or thin looks better but I've never subscribed to the thick edge highlight followed by a thin one.
Especially not on rank and file models.
Why don't you think it looked right when you did it? Sometimes you have to unfortunately do most of the model before you see if it works for you.
