First of all how fast are you in your triathlons?
If you're riding at over 20 - 22 mph, they may make a difference. Otherwise they're just heavy and nothing else. They look really cool though. But unless you're doing half iron or Iron length tri's where you'll gain an additional 2 mph if you're doing 22mph+ (most benefit is in excess of 24mph).
Next, high end wheels will perform better due to better bearings, lighter weight, better aero characteristic, proven r & d, and so forth. If you are simply wanting to go faster, getting the cheapest deep aero rimmed wheels may not give you a significant speed increase. especially if you are a sub 22mph triathlete.
Lastly, the depth of the rim can be a deeply debated subject on its own after the first 2 thoughts have been considered. But the wheel depth is definitely the last consideration. Deeper is better... IF you are faster already. ...and, IF its not windy. ...and, IF its not hilly.

You're in New England right?
I personally think that if you've satisfied the first 2 criteria, probably zipp 404 firecrest CC wheels would be the deepest you should go. But you may get more speed from lighter slightly less aero wheels.

Mostly have fun.
