The Spiros will most likely last way longer than Innovations. Also, some use 4/4 sets on their 3/4 bass to decrease tension. I'm leaning towards Spiro weichs for my next setup after trying Honeys (which sounded great on my bass, thumpy but a little thin sounding on the G string), Evah weichs (nice clarity but not quite the volume) and the current set of Velvet Animas (complex, dark, loud and thumpy, yet lower tension). My elbow injury wont let me run the high action anymore.
