Oil: synthetic or mineral?

Last time I changed the oil I used a fully synthetic Castrol motorcycle oil. Now the clutch sometimes slips when I'm hard on the throttle and the clutch is partially enganged.

A person I talked to said that he wished he had a nickel for each time he had to tell people that these bikes should be kept on mineral oil alone. He is something of an old-time cross legend here in Norway (currently races a YZ426) but his advice goes against pretty much everything I thought was true about mineral vs. synthetic oil.

Does his advice make sense, or has he just banged his skull into a rock one time too many?

What do you people use?

Hi , if it helps , I am using Putoline SYNTEC4+ and have done so since new. I have done nearly 2000km now , both on & off road and have no problem at all with clutch slip or anything else.
