1.) Some brands of trekking poles have fatter tips than others - we need to make sure the tips of your trekking poles will fit into the ridge pole. 2.) We need to know if they are adjustable to at least 135 cm.  If not, we can supply (at no extra charge) a custom ridge pole that will make up for the shorter trekking poles - this does add about 1 ounce of weight to the tent.
