I used this gauge of ultex back when I was a serious pick guy for about 2 years while in a band that lasted for 5 or so. That's a lot of commitment for me. I like that the ultex picks slide off the string but not off your fingers. The sharp point lasts incredibly long and can also be used to fish bad truck stop food out of your teeth when you run out of floss between tour stops. the overall tone is a great compromise between vintage celluloid (fender) and tortex. They don't crack like thinner celluloid picks and they wear a lot slower than tortex.
The .73 gauge was awesome for me at the time. I liked the slight flex they had for circular picking and they added a really nice amount of click to my chugging when playing power chordy rhythms through a raging superlead. I started to get back into heavier picks a few mm at a time and now like genuinely heavy picks because I got a bag of heavies for free from Fender way back when and I'm notoriously cheap about shit like picks... but given my druther in plastic picks I still dig these or the 1mm ultexes a lot. You should try 'em if you haven't.
