Jones, opinion
IMO linear is always best for trendlines as the space is always equal, opposed to log being farther or closer depending on current price
Stockcharts has a setting to use either
Trendlines could still be used with log but i'd expect them to be less accurate
I like to use horizontal supports and resistances better anyways. But triangles, wedges etc have their place.
GTE is a good case for that
It's all personal preference really. You learn what works over time and practice
