Is it worth using Specials in first 30 seconds?

[GabeRainery]

I am asking this in regards to top level to high level in competitive Splatoon where most teams have cooler out and grabbed by 3/4 of the team in the first 20-30 seconds of the match. Is it worth using an inkjet, zokka or crab etc in those first couple of seconds of the match or is it better to just fight after cooler with main weapon +sub win the fight and keep your special for second fight or lose and still have 90-100% of your special ready to go on defense. No Splatoon game will be played perfectly by both teams and in cases where both teams stall getting a kill + momentum going after 30 seconds of that match I can see a special being used to force a kill. But that is why I ask is it "OPTIMAL" to use a special to force the kill? Or is it better to save it for snowball pushes or defense.
