Is there any reason I would not want to take it?
That's really something you'd have to tell us. Why did you want the CLI?
The only reason I can think of is if someone knows that they can't manage the additional credit.
Another reason not to take it might be if you expected your income to rise a lot in the near future (I know it just has) and if the issuer has a limit on how often you can get a CLI, taking one now may mean a delay in getting the big one you want. But even then a smaller increase for longer might be worth it, so yes, take it!
