Glad to hear you're seeing great results from your value trigger job!

If you do have light strikes, don't abandon your efforts.  I'd recommend a set screw from a hardware store loc-tited in a little further than the current factory strain screw is. 
If not that then try a full-powered Wolf spring with the factory set screw.  It's worth the extra $10 try.  The full-powered springs can still be much lighter than the factory spring - it was for my S&W 617.
