My taste buds seem to be changing again. Here of late, I've had to change my percents on everything. Makes no rhyme or reason though, because I have to go up on some, down on others. The good part of that is that I'm still finding mixes that I like really well.
I'm also wondering if our equipment isn't playing a part in that as well. I think almost every one is benefiting from better equipment design, regardless of what they're using.
When I went to the 804s I had to lower my nic level and lower the percents in some of my mixes. Recently I went to mechs because of two lava tube types in a row quickly developing button problems, so now I'm wrapping my coils at lower ohms to suit the mechs. I'm thinking that's playing a role as well as changing tastes.
Equipment plays a huge part in flavor. A cotton filled carto does a poor job of delivering flavor. Kanger T3 clearo will do a much better job of delivering flavor and a rebuildable atomizor (rba) such as a kayfun would be the ultimate flavor delivery device.
