If you want a string that is not as thin as the 370's and has more body.....try the 380TX's.They have about the same tension as the Spirocore Weichs or medium pizz or hybrid Helicores.
I used the 380 TX's for a while for pizz on my old Kay and liked them. They are supposed to be good for arco too.

Ooops sorry....I did not intend to start a new thred on this.
