Best leather conditioner?

[Mince Pie]

My pot of Leather Genie has unfortunately been lost and I was wondering what everyone else used before I replace it. I've tried ko-cho-line and horseman's one step and wasn't amazingly impressed by either

I like Effax leather balsam.

I was given a tin of Passier conditioner by the lady who does the Schleese saddles, and it is lovely. All you need it to wash the leather in warm water and then wipe over with this stuff and you have lovely soft leather - she should know her stuff, she deals with saddles as a profession.
