If you are comfortable with these numbers I would go with them.

We typically keep people very conservative at a first meet.

I feel these are numbers you can hit with room to spare.
That is the best way to go at your first meet.

I advise against going any heavier.
Feel free to make smaller jumps if you are feeling nervous.

Or, I can even lower the numbers.

Remember, this is your first meet and all you are trying to do is successfully get a total to build off for the future.
