Yes I think that you should use it now that you have it !!!! However, when you are done using that bag I think that you will have gained experience that will help you chose a great bag that is perfect for you and you only...If you hike in a lot of rain (and I do) I would recommend that you stay away from down. Although down is probably the best insulator it is useless if it ever gets wet. Synthetic insulation will hold it's insulating powers 100% better than down will and unless you are very experienced, a down bag will be very very hard to keep totally dry forever. It just won't happen...Hope that helps...sabre11004...
