Interesting that two are yellow, and two are lavender, the two colors that, at least in modern roses, have been the most susceptible to disease. But I can vouch for the health of True Friendship (and Ping Lim's roses in general), as well as Easy to Please, which was one I acquired in one of those "5 for $25" specials a couple of years ago.

I need more roses like a hole in the head, but I'm now looking at Arctic Blue and Pretty Polly.
