@Mister Cbass, when I first responded to your questions here I was hesitant to specifically mention SilverSlaps because it sounded like your muscial target was more modern/new jazz and orchestral with bowing...
I've been using SilverSlaps for about 2 years now, the SilverSlaps E and A (under SBW Deluxe D and G). The SilverSlaps E and A have excellent clarity and volume and notable growl and project the exact note very clearly which was what I needed.
The SilverSlaps weren't originally very usable for arco, but I kept trying with generous rosin and a relatively tight bow, and after about 2 weeks they began to really respond to the bow (the SBW Deluxe D and G have always been good for arco). I mostly play arco in practice for intonation, but will also occasionally bow a bit on stage for variety and for special effects in performance.
I'm playing a 1930s aluminum Alcoa, so finding strings that didn't sound at all metallic was important to me, as well as finding strings that wouldn't hurt my hands with pizz, light slap and a little arco. The mix of SilverSlaps under SBW was just what I needed. This synthetic mix has been lasting for 2+ years with no signs of wear so far. I amp a little on stage as needed, but also jam a lot in totally acoustic jams; my genre direction is roots/Americana including a lot of bluegrass, Gospel, country, folk, old jazz, light swing, etc., my primary venue direction is bluegrass festival stage, jamming, coffee houses, church programs, etc.
A person's musical direction, including general targets for genre and venues (and amplification needs), makes a big difference as far as what strings to recommend. Some of the early responses in this thread have alluded to this, but just to be clear, what and where are you seeing yourself playing as you move forward with string selections?
