I had them - I was big fan of Gerry Winskill’s UK Farmstrips series in FSX so I bought these - 3 packs - to have a look at.
But I found that whilst yes, they do add things to the strips, they have a hit on performance. In fact so much it made my normally smooth VR flying a comp[lete stutterfest whenever I got within 10 miles of any of the sceneries in the pack.
So I moved them all to a temp folder and tbh they have stayed there ever since. I found that the default strips (and there are tons of them - see screenshot from East Anglia alone and my first strip tour, below) are just as difficult to find, with enough present to recognise it is a strip (where you can actually do so in RL) and the nav is actually more difficult and therefore more fun, due to the extra stuff that this pack puts in, being absent - if you get my drift.
So whilst they look good, they are not opitmised.
I did some research and found that this was the case with packs he had done for previous sims and that he was aware of the performance hits, he did nothing to adjust them - so I decided not to buy any more of his scenery. Shame for him, 'cos I was set to buy everything.

These aren’t all the strips, either - just those that have only grass runways. Some are metalled, even if very short, and I don’t use those.
