Hi Rick....
I only used the hybrid musk class as an example. There are a lot of people growing HTs in the PNW. I just don't know which ones are best for your climate. If a rose has more petals, you want to the site the plant where it gets more sunlight during the day.
You are correct in that the photos that show that V-like form are partially open blooms. That is also what is called "exhibition" form. The are a lot of rose that will open high centered and when fully open have a more "flat" or "cupped" bloom form. Bloom forms come in and out of fashion just like men's ties. Right now, the high centered form is somewhat out of fashion, but that doesn't mean you can't grow those roses, if you can find them. More about that later.
Here's a short list of red HTs that I found listed as available on some Washington nursery sites and which seem to have a good reputation for disease resistance, but that is only true for where they were tested and where people have grown them and passed along the information:

This rose is supposed to thrive in cool weather conditions. I know it doesn't like my hot climate, but I am going to move my rose to a different site in the garden and see if I can give it some afternoon shade.

This rose seems to have a good reputation for disease resistance in several climates. I know the blooms on my young plant fried in my triple digit temps, but it's young.

This rose has a reputation for being a very solid plant, but I don't know about disease resistance in your area.

It's an interesting rose and loved by some and hated by others. It was introduced to the US when Jackson & Perkins was located in Oregon. It may do fine in cooler weather.

I can't comment on this rose because I don't know anyone personally growing it.

Another rose with a reputation for liking cool weather. I don't know about the disease resistance.

I've been told this is a solid plant, but again I don't know about the disease resistance.
Here's a link to the Olympia Rose Societies list of best roses ... remember, the list is always skewed towards exhibition and not necessarily towards easy care garden roses.

The thing is that the rose industry in the United States has entered the dark ages of roses. Since Jackson & Perkins went bankrupt and pulled Weeks Roses into bankruptcy, too, there are no rose companies in the US with an active breeding program and many of the roses being introduced are the roses that were in the pipeline but had not completed the testing program.
J & P was purchased by a venture capital company and I haven't heard any good news about them as a supplier. Weeks was purchased by Gardens Alive. I have looked at the roses from the few nurseries near me and have found that the quality of the plants vary a lot, probably due to the subcontractor which is supplying the roses.
A lot of the roses introduced in the last 50+ years were only tested as budded roses. What that means is that the seedling was selected because of its bloom form and then budded for further testing. The rootstock often provided more vigor for the rose to make it a viable plant. Without that additional vigor, the rose probably would have never made it to market.
Now, there are many nurseries selling these roses as own root. I haven't found any documentation that specifically says this rose, which was once only sold as a budded rose, will be a vigorous plant when grown own root. It may be a good plant own root. A lot of roses were budded when they did not need the additional vigor of a root stock simply because that was the rose industry's method of bringing a rose to market faster.
There are some very good nurseries which really do test for this kind of thing, so checking them out is really worth your time.
I hope this helps.
Smiles,
Lyn
