I have no problem with any kind of bet you want because the fact of the matter is that Issei already had a  RG with Sairaorg, but not  with Diehauser. Just don't be a Sore Loser afterwards like the match with Rias. After beating the Champ facing of one the strongest beings a God no less unlike any he faced before facing off against his rival sounds very climatic for the plot.
