Definitely. 45-105 Dunlops are very easy to play without being anywhere near floppy...nor would they ever be mistaken for bridge cables. I have this set on my Moollon P currently. If you want a little more girth and thump Dunlop does make a 50-110 set that is excellent. Jamerson gauges without Jamerson tension and stiffness(feels about like the 760fl under the fingers). I own and love all three Long Scale sets and I also run their short scale set on my Serek Midwestern.
I tested somewhere around 15-20 sets of flats during the lockdown. Dunlops and TIs were the only sets that the honeymoon period didn't wear off. They've performed exceptionally well for both recording and live band situations. Based on the fact that you're looking for an E string that sounds like it fits in with the set without waiting 6-8 weeks for the rest of the set to go dead...I recommend the Dunlops for that reason as well as bunch of others. Really a great set of flats that straddles the line between traditional and modern flats. Best of both worlds IMO/IME. It's a bummer that the price has gone up so much. I got all my sets for between $30-$35 each. That said...If I need another set for whatever reason...I wouldn't hesitate at $50. I think you're barking up the right tree.
This was Ed Friedland's description of them for a Flatwound Round Up article he did back in July 2020...
Dunlop's flatwound set is the newest addition to the field in this roundup, and while they exhibit several characteristics of the new breed, the tone is decidedly old school. The string tension is well-balanced across the set, falling on the lighter side of medium, but they exhibit none of the roll-under-the-fingers that some lighter-tension strings have.
The outer wrap is not highly polished, giving the string an earthier feel that says, "go ahead, dig in." The Dunlop Flats produce a clear fundamental with great intonation on the lower strings, with a punchy attack that makes them perfect for old-school tone.
