Deb, when I make pizza dough I use rapid rise (the original recipe called for instant yeast) I like
the results of rapid rise compared to instant yeast.
I don't think I may have answered your question but I am hoping this helps you.
I normally don't do this but when I have run out of instant yeast I use rapid rise yeast and vise versa and to be honest I have NOT seen a difference in taste or texture.
