I've been using TSi2 for 3+ years and absolutely liked it in many ways include how it sounds and feeling at impact. It sounds slightly metallic and crushing sound that is relatively loud to hear from a distance. Recently I heard good things about GT3 drivers and wanted to try it with the same shaft I'm using on TSi2 which is Tour AD GC 6S. My first impression on GT3 is that it sounds and feels so different from TSi2 at impact. GT3 sounds way more dull and carbon / plasticky sound and muted as if the head is wrapped around with a rubber/plastic. From a performance perspective, I got similar ball speed/distance but seems a bit better side spin rate.

When I watch YouTube clips on GT3, it sounds not as muted as mine but not sure whether that's an effect of how it's recorded. What's your experience and opinion about the sound and feel of GT3?
