The problem here is that your CS will not add a RB stack in this scenario since you are already capped at 2 from Berserker Rage + initial BT crit. My suggestion would be that you wait and see if your initial BT crits or not before hitting BR, because if it does you will be enraged for the DR and the following reck (non-glyphed) makes the CS a very likely crit leading to a second stack of RB. This could save you the BR entirely, while still maintaining the same opener in case your opening BT crits.
