I've only had the "PEPESR" strings on my guitar for a few days, and I'm really enjoying them. They're not big and bold like Hannabach 815, but they're warm, easy to listen to and easy on the fingers. These are HT nylon, but they feel like normal tension compared to other strings I've played.
They remind me of maybe La Bella 427, but in a much better version because they're thicker and have good intonation. They're lovely. I'd be curious to hear if anyone agrees or disagrees with me.
Some great strings feel a little wirey to me and most strings IMO have a metallic tone to them, but these don't as much. I really like them, but I also know that good strings have to stay likeable over the test of time, so we'll see how I feel about these after some time passes.
Two thumbs up so far, but that comes as no surprise as the Romero family is probably very serious about what they are willing to put their family name on.
