Swapping BT for PD doesn't really change your dps that much (assuming both are your first item anyways) PD gives movespeed, while BT gives better sustain, ability damage. Pretty much your choice. PD also comes in smaller pieces if your having a tought lane, but then again if your having a tough lane, sustain will help you stay in it better, and if all your doing is a few attacks here and there then BT will be better as PD is for hitting with your W more while it's up, which may not be feasible depending on your lane.
