Okay folks . . . I have read posts on both of these strings until I am cross-eyed. For people that have tried both strings, please share your opinion for both pizz and arco as to which string you prefer and why. Also, if you have tried both of these strings and like yet another string better than either of these, that would be great information as well. My basic profile relative to strings: - Two-year-old Christopher hybrid bass - Play almost all pizz but want to play more arco - Bob G. German bow Strings tried to date: - Helicore Hybrid mediums - no redeeming qualities on my bass - Obligatos - Liked very much until death at 8 to 9 months - Compass 180's - On month 14 and still in great shape, overall favorite but looking down the road at next string experiment Thanks all for your input . . .
