All I'm saying is if you are planning on learning to lead trad, your going to want to have those standard ovals anyway. Wired stoppers have been known to open up wire gates and fall off. This is less likely to happen with the standards.
The spine of the standards are a perfectly round section, whereas the Dovals is an asymmetric section. As a consequence of the smaller size and the sharper spine, you'll get a slower rappel with the Dovals. As Tom says, buy the Dovals and try it in your garage.
