I would prefer Chorley over Guiseley. Even though we beat Guiseley 5-1, they are a better team now than they were then. Plus our record there is poor, and we lost against them at the same stage in 2011.
Saying that it's all about form in the play offs, and if we can hammer Leamington that will set us up nicely, especially if we can keep finding the net at home as often as we have this season.
