Is a 302 or 301 redirect better for this IIS rule?

Following this article: Redirecting ASP.NET Legacy URLs to Extensionless with the IIS Rewrite Module

I added these rules but I'm not sure whether it is better for SEO to have the first rule do a "Permanent" (301) or a "Found" (302)

            <rules>
                <rule name="extensionless" stopProcessing="true">
                    <match url="(.*)\.aspx$" />
                    <action type="Redirect" url="{R:1}" redirectType="Found" />
                </rule>
				<rule name="removeextension" enabled="true">
					<match url=".*" negate="false" />
						<conditions>
							<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
							<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
							<add input="{URL}" pattern="(.*)\.(.*)" negate="true" />
						</conditions>
						<action type="Rewrite" url="{R:0}.aspx" />
				</rule>				
            </rules>
