XF 1.2 Hide Ads on Members and Recent Activity

[Quiver]

Ok, so I have a below_top_breadcrumb ad that annoyingly won't allow 728x90 when a sidebar is there but does without it. I don't want to be stuck with 468x60 so I'm trying to get it to be 728x90 but 468x60 on pages with a sidebar. Currently I am trying to find out what the conditional is for "/members" and "/recent-activity" pages. Anyone know?

I tried <xen:elseif is="{$contentTemplate} == 'member_list'" /> but it didn't work?

Ignore me:
<xen:if is="{$sidebar}">
This content will show on pages with a sidebar
</xen:if>
did the trick.
