Browser back button and subcribing by URL

help
1

I have a problem.

Whenever I browse thru my app using browser’s back and forward buttosn, my page display non-filter subscribings for seconds before the this.params condition kicks in.

Router.route('/:sub_url/', {
name: 'tournament',
template: 'tournament', 
     waitOn: function () {
         Meteor.subscribe('People', this.params.sub_url); 
         Meteor.subscribe('Schedule', this.sub_url);
         }
});
