My 2020 (Chinese made) Tech took me by surprise (last used 11 months ago). I'd forgotten how light it was compared to my 1940s Flat Bottom Tech. The loaded 2020 Tech head weighs in at 11.2 grams, versus my top favorite 1940s Flat Bottom Tech at 25.2 grams (loaded head).
Once the weight difference registered (almost instantly), technique tweak came into play and all was well.
