To be honest, I don't think you'll get a WWW. You did a solid job matching their strengths and weaknesses (I'd watch out for the movement, though. Nothing a movement glass wouldn't address, though.) You have some options here, though.
Option 1: Stick with this match. Use a movement glass (100k) for the best chance. My best guess is that you'll end up with a EWE combo, though. It's hard to say how the mare will produce because she's only had 2 foals. She could produce better than EEE if she's bred to a sire that is on a breed leaderboard. The two sires of her foals are not, which makes it hard to see her top potential.
Option 2: Find a sire in the top 20 on the XLB (if you want an X foal). They go for 20-40k, so it's a lot cheaper than getting a movement glass. Plus, they are stastically better sires who produce more WWWs. The stud you picked has only produced 1 WWW in his entire career, and frankly, the chances of him producing a second in this match are not high.
If you're open to finding a new sire, PM me if you'd like help with matching. In the end, you'll have a much higher chance of getting a WWW, and you won't need to throw a glass in to bolster a weak stat.
Moving forward, I cannot emphasize enough how important it is that you breed to top LB sires. Sure, a non-LB sire can produce a WWW, but they're inconsistent. And, 95% of horses on leaderboards are sired by ABLB sires. It is worth your money to invest in a leaderboard sire if you want a WWW foal who will produce more WWWs for you.
