Welcome to Just Answer. You can use the comforts (spinosad) at the same time as sentinel (milbemycin oxymine). In fact, a very similar combination is now marketed under the name of Trifexis.

Here is the link.

The only thing not in the Trifexis is the lufenuron. There wouldn't be any reason / toxicity for using the comforts at the same time.
