Does anyone have any experience of the finer points of the House of Cheviot Katrine Line?

I think the line must now be discontinued but I have found a retailer selling some at a good price and was thinking of adding some to the stable.

I do generally enjoy "decent" hose: my base line for "decent" quality is the House of Cheviot Rannoch line. I do prefer spending that little bit extra for hand knit hose (like the almost unwearoutable offerings) but in this case I want some "not too fancy but relatively sophisticated" (i.e. not heavily patterned) hose for black tie events; I would prefer to spend my extra pennies on "day to day" hose that will see a lot more action! I do have some (Rannoch) hose that can be pressed into service but, as mentioned, I was considering adding these so that I have some more colour choices.

In short; is the Katrine line of comparable quality to the Rannoch line? Any observations, comments or experiences would be helpful.

Kind regards
