Hello Frank,
We have had great luck with your rings in all three of the DL 30 that we have installed them in.Better compression right off the bat.eaiser hand starts and 100 to 150 better RPM.They will only get better. Am flying the DL 20 now a real little monster.I believe DLE did make a improvement in there rings but still not nearly as good as your.I will be ordering more rings for the DL30 and also DL 20s.
Had to close C&H after 30 years.I am sure you have heard about my bad luck with a surgery this past summer.Staph in my sternum.Must have more surgery.
Closed partly because of health and far east.If you no what i mean.
Merry Christmas and a good new year.
