hi, just got my set of JPX E500's (thanks Chris & Jacque). had a slight delay from customs but finally got them and they look and feel great. took a quick spin out to the range to compare to my MX-23's. i always thought the MX-23's felt great but there is a difference when compared to the E500's. the MX-23's almost feel "clicky" in camparison. so far, the forgiveness feels about the same. maybe a slight edge to the E500's but haven't spent enough time with them to tell. distance seemed a bit longer. probably due to the stronger lofts.
fit and finish on the E500's are terrific. noticed the serial numbers are on the ferrules while they are etched on the hosel for the mx-23's.
overall, they look great although i kind of like how the pw, 9 & 8 on the MX-23's look more like muscle backs as opposed to the E500 which look like cavity backs throughout the set.
club play tommorrow morning so we'll see how it goes with the JPX E500's.
