Tried the Helicore Hybrids in `medium` gauge and loved the sound, especially the arco response in the lower register. However, I found fingering for pizzicato rather stiff and uncomfortable, particularly for fast jazz passages (Over a period of time they hurt!). A friend who is fully pro also tried them and felt the same. Has anyone tried the `light` gauge Hybrid? I`d really like to know how they compare both for sound and feel with the mediums. I have gone back to Spirocore lights at present, but the bowing response is not as good in terms of sound, especially low down on the `E` string.
