New club for Christmas?

Thinking about treating myself to a new club for Christmas... maybe a Titleist 60/07 lob wedge to replace my MD golf 60 degree one, and so I can buy the better grooved club before they're banned.

Is that a good idea, or is it likely to not be much better than my existing one?

I have an MD lob wedge and a 56/10 Vokey sand wedge. If I was to change one to match the other, I'd end up with two MDs. Says quite a bit.
