I received two Es, both 173, ones the LE and ones stock. These are my first Electron discs. I only Putted with them, in my yard and at the course, and these are my initial thoughts. I'll draw comparisons to Judges.
I'll mention quick that they are put together very well. No obvious creases, consistent between my two. Was worried with the previously mentioned issues. All good!
The plastic feels pretty good. Pretty grippy, Medium give, kind of soft. Already got a decent gash in the rim of one (hit the side of a number plate square on top of a basket). Not unrepairable. I'd liken it to a blend kind of plastic, maybe a little softer. I think it might be too soft to be throwers, but good for putts. The premium envies are all perfect for throwing though, so I'm ok with this.
I have (or have had) around 7 envies in the various premium plastics. I'd say they've all felt pretty consistent, less my most recent P, which has a little more dome and bigger bead. Like already mentioned, these Es are shaped a little different. The two I have feel similar to each other, but shallower than usual. The 'bead' is not near as prominent. The bottom half of the rim is flatter, where other Envies have a bit of a concave shape to rest a pointer finger. The dome still flat like an Envy. I would say the inside of the rim is still slightly plussy like usual. Again, feels shallower.
I really like the feel In a fan/Putter grip. It's shallower than the judge. I kind of wish the bead was a little more prominent, as I like to rest my finger there, but my stroke didn't suffer. The feel was intuitive to release a faster spush/spin putt, IMO. I was expecting it to be more OS, at least as it slowed down, but I thought all my putts flew very straight, not unlike a fresh judge. Felt like these could give me a slight edge on longer putts vs the judge with a little less glide, faster flight, and great shallow feel. I will most likely not throw these, but only use them for upshots and putts. Pumped to get to know these better!
