The only reason I can see to use high wattage builds is stuff like large elaborate coils with a "ton" of metal that needs to be heated. Even there, things can be interesting. If I hit a dual fused Clapton with a preheat of say 75-100W (and that is far from normal vaping) for 1 second I can drop everything back to 40W, and if in TC, watch the wattage go even lower to maintain the temp.
Do the more "nooks and crannies" to vaporize more juice really make a big difference in that setting? Not very much. Almost all my vaping is done with Clapton or simple round builds. It all depends on the chamber and chimney, along the airflow of the specific tank. I haven't found large coils that need 1.2kW to heat up really makes any difference other than increase my electric bill.
