A few weeks ago, I was presented with the opportunity to wear test something from the Aqua Gear Swim Shop (http://www.aquagear.com). The company has a great website with a feature that asks if you need help right upon logging on. You can choose to live chat with a representative, or just click no. There are many educated people that can help you choose the correct paddles, bouys, or any other accessories.
The accessory I needed was paddles. I choose the Finis Fulcrum paddles, which have 5- sizes based on body stature. I have the large, white paddles.
Another aspect I love about the paddles is that they are good for all strokes. When swim coaches are having a bad morning, and they assign a butterfly set with some paddle work (or IM), I do not mind using these paddles for any stroke. Using other style paddles has made my shoulders scream in agony! Being a triathlete, I never truly enjoy a butterfly set, but when paddles are added, I think the lifeguards become on edge.
One other note about Aqua Gear is the awesome customer service they provide. As internet shopping becomes more popular, internet- customer service will become paramount. I cannot express how easy and helpful they made the process.
