i say sounds frist and just drop it but if you are 100% sure you want to bag it, your gonna have to bag it frist because your doing a blowthrough, because when it comes time to bag it your gonna have to tear that sucker out of your bed becuase the bed needs to come off of the frame so they can work on it, so its up to you, i follow the rule of thumb do it right the frist time, and only do it once.
bags is fun and all and it looks super cool when its layed out but trust me everything has been done already there is no sense in playing catch up with everyone else so i say walk a different path and load it up with some sick sounds and give her a nice drop with some sick wheels
