2001 supra launch

Im picking up my first boat on saturday. I have a few questions about it. It is a 2001 supra launch. It does not have the hydraulic wake plate and it has the rear ballast. No ballast in the front. im just wondering if i will be ok with just the rear tank or if i should get a extra sac and throw it in the bow. Any suggestions would be great. I am very excited because this is my first wake boat and im stepping up from my parents old I/O.

Thanks for the input.
