Daddario ECG25

I used these for years on full-body jazz guitars and semi's. I always found them absolutely reliable and well-made. I often changed the top two strings for something (even) heavier though. If you want the mellow jazz sound, without the edge of round-wounds, these are probably the most cost-effective option. I'm not sure how they'd sound with a light or medium pick though (I always use heavy 2mm picks). If you're a hammer and pull shredder, or a full-time bender, you'll probably find them too heavy. I've recently switched to TI Jazz Swing - although they're more expensive - due to their feel and tension. These things are very personal though and choice depends on so many things: how you play; your guitar; pick; the sound you like, etc. I'm afraid there's no alternative really to trying different string-sets yourself. If you're into flats, you should certainly test these out. But check the weight first - Chromes come in a good variety of weights. And, if you like these for say, EADG, but want something heavier for BE, d'Addario make singles, which greatly increases flexibility.
