So my 1994 is nearing on 15 years old. The leather is of course old and has been kept up with the conditioning it needs. However of late it seems to be getting more cracks in it, what are some recommended products I could use that would help my case?

Once it'* cracked, it'* cracked. Best you can do is keep it conditioned so it don't crack more. Leather whips should be fine.
