You don't! Do it from your first gas switch (21m for a "normal" dive)

Yours would pop up in the same place as all the other bags deployed from the wreck (think about it). All divers are drifting in the same direction, in the same current and at the same speed. Even in a 2kt current, deploying from the first gas switch won't put you far away from the wreck. And if you are diving in a 2kt current, somebody has f***ed up!
Having said that, we do tend to deploy from the wreck, because that's what the skippers seem to prefer. In that case, I would always prefer to use a reel in preference to a spool. Once at around 9m, other team members then deploy their DSMB's (using spools) resulting in the usual underwater knitting competition at the 6m stop.
A word about deploying DSMB's......Since we dive as a team, deploying a DSMB is a "team event" too. When time is up, we leave the wreck and start our ascent. One team member assembles DSMB to reel/spool, offers DSMB to buddy and he inflates the bag with a little purge of the primary reg (switch to backup for this). This is the way I prefer to deploy. Then, reel changes hands between team members, depending on who's doing what (e.g. during gas switches etc.)
Exact procedure depends on the skipper. Some like one per team, some like one per diver. Some like to deploy from the bottom, some from the gas switch The DSMB is primarily there to mark your position for the skipper, so he/she has the final word on this.
