Give Zaino Z9 and Z10 a try. They work awesome and is some of the best smelling leather conditioner you will ever smell. I even use it on my leather couch. It makes my entire house smell like leather.
I also like Leatherique for deep conditioning. I use it on my vette seats twice a year and use the Zaino monthly in between and my vette seats have 13000 miles on them and literally look like new. Everybody comments on how good they look and Z06 seats are notorious for wearing out prematurely and are usually beat by 5000 miles.
I haven't tried the Leatherique on my Vipers seats yet.
