If you do not want to put forth the effort of applying elsewhere, then the flow will help. Likewise if you have a bad record with multiple checkride failures or a criminal history.
If you have a good record, there is really no reason to wait for the flow unless you really want to work for the parent company.
This brings up another important question that may not have been discussed so far. Is there a probationary period after you flow to mainline. If there is they will just use that to purge all of the undesirables that they don't want.
