I have read several threads on this and made a few of my own. This one is different as it addresses the Consistency of the G and E (or E/C ext or Low B as well) as compared to the A and D. I have not had problems with any of the Pirastro strings I tested as far as the D or A goes. I have however had various tonal problems and a few playing problems with 'either' the G or E with some sets on Some Basses. Also, when I re-cut the Bridge top of a Bass taking the strings on and off a few times, I notice the G becomes a bit Scratchy on the Flexocors. Frequent string changes can kill any string but this is the best bowing G in the business from what I have played. I used some Jargar Blues back in the mid 70s on one Bass that I remember. It was not for Bowing but rather for Jazz. They sounded 'OK' and so did the Bass. I don't recall trying them on my Italian Bass which was my main instrument so a true test it did not get. After hearing about this darker sound they get and the fact that I tried a 5er with only a B Jargar mixed with Flexocors makes me wonder if I need to try them again. In the 70s-80s I did not play to many Orchestra things at all as compared to Jazz, Pop and Commercial Gigs. Now in my '2nd musical life' I play mainly in Orchestras with a few Jazz Gigs on the side for which I use a different Bass than with Orchestra. So Francois (and other Jargar lovers), Should I try and replace my Flexocors with Jargars? I would need the Blues or maybe the reds on one of my Basses (now with Stark Flexes). I also have a 5er and Ext. Basses to fit so there is only room for one sound with my Bow. This is like the Iron Chef of Strings here. "Who will Reign Supreme" for the Ultimate dark, smooth, consistant Bowing Shring for the Orchestral ContraBass? Flexocor or Jargar ?
