What should be Career path for switching from PL-SQL developer to Oracle-ORMS Technical Consultant

Hi All,
I have 4 Years of Experience in Oracle. Out of which 3.5 years in PL-SQL and 6 months in Oracle product RMS.
Currently working as a PL-SQL developer in ETL Project. I am getting opportunity to go ahead with Oracle RMS as I am having 6 Months of experience in it.
So I am getting confused to go ahead with it or not, as Oracle-RMS will give me an Domain Experience but Oracle PL-SQL with ETL give me growth in technical Field.
So I just want to know what would be the future in both the technology or which path should I chose with respect Career as well as Financial growth.
