Fascinating Warren! You choose many outstanding roses for your crosses and the result is unbelievable.
But I have a critical question concerning f1 f2 etc. As I understand it every new cross creates a f1. F2 would be the growth of self pollinated f1 with a stable growth pattern. There seem to be virtually no f2 in hybrids while it would be very interesting to search for it I believe.
'Big Hearted' looks very good Warren! Is it healthy? And the fragrance? Others You posted photo's of today are looking good too. What decided you to mate these two roses? Fragrance? I would like to see this-one in real-life!
