Planners' Opinions Needed!

Hi everyone. I am doing some marketing research for a group of city planners thinking about starting a consulting group. The group's proposed name is taken as a .com domain name, so they are thinking of adding the word plans or planning to the end. I suggested asking people in the business, so they advised me that Planetizen forums was a good site to find a collection of planners.

So as not to identify the group, I'm going to insert "proposedname" for the company name in the domain.

What do you think? Which seems like the better fit?

If you have other suggestions, I would welcome those. Thank you in advance for your input.
