Sorry I missed this peter pan. I have thought of blended sets but have now pretty much converted to 9/42 on all my working guitars. My big fear was playing slide on such light strings but with some work on a lighter touch it seems pretty much fine, though more work is needed. Main thing is I find I can move quickly more easily. Experienced that recently on sultans of swing ... The last solo used to near kill me but it's a lot easier and more fluid with lighter strings... So I am converted.
