IMO the notch coils are not well designed and you may not get any better performance from TC mode so try not to be surprised. The thin Stainless steel tubes used to create the notch coil make for great ramp up and the surface area makes for great vapor production, however the lack of extra wire grabbing juice (like in Clapton coils and the like) allows the notch coil to heat up too quickly and burn the juice, with two 5 packs of notch coils I've had nothing but the same results in both TC and wattage.
