I had a ton of fun with the 58* Mid today. I was very, very comfortable from the first shot. I think it fell right into my expectations being easy to hit and how it sets up. The RTX4 58* Mid was a favorite of mine last season due to very crisp turf interaction in mixed conditions and the fact the I could really keep the leading edge low on hardpan and when opened up.
When ordering the heel-toe grind with standard leading edge, I was trying to get the Mid to sit a little closer to the ground when opened up while keeping plenty of available bounce. I didn't want the leading edge too sharp as I play in quite mixed conditions. It was medium-soft today with lots of recent rain still moistening the turf. I once again had tons of spin available from the fairway, rough, and greenside. The bounce was instantly my friend and it played just as I hoped today... plenty forgiving in softer ground but still sits nice on hard lies and vary playable from just about anywhere.
I forgot my towel and the course was wet with new granular fertilizer applied... I had to go shopping, cook dinner, etc. before just now wiping it down and the face is pretty trashed out from the fertilizer. Whoopsie. The main point, is that the club was wet during the whole round and covered with gunk... I was using the wet turf with half dissolved fertilizer to wipe down mud and grass after shots having forgot my towel. Not the cleanest of contact conditions by a long shot. Fresh UltiZip grooves don't care - I was leaving shredded urethane in the grooves on approaches from the wet rough and fairways.
It was hop and sit tight conditions in general at the course today. Greenside I was not the sharpest but I got out exactly what I put in, and the club played fantastic. I hit a few open shots and it sits great opened up. The bounce is general is exactly what I was expecting and hoping for, a bit more generous the the prior gen RTX4 in my mind, but when opened and off tighter lies the leading edge is plenty close. I think the relief grind really adds something to this wedge. I like a close leading edge... just not low bounce for our softer periods on course. I even played a crazy little toe-down chip just to see ho it played and it worked out. I never play those, was impressed.
My one omission is I forgot to hit out of the sand all day... did a good job stayed out of bunkersand forgot that I was supposed to be testing from them! Next time... a little sandblasting is needed to clean up the fertilizer rash.
Overall it was a great first outing and TBH I expect great things from here. I love the ZipCore lineup and the raw, hand-polished finish and hand ground options are just outstanding.
The spin is crazy nice. Interesting on the wet performance. I've played zipcore wedges quite a bit this year. I've taken dead aim for hop and stop over and over. Playing partners have said things like, "that's not possible." But I also find these easy to control spin and get release when needed. The confidence to hit shots knowing the clubs will provide the consistency is fantastic.
I still find my eye catching the hand polished Tour Rack zipcore when I look at my bag. It is the best looking club in my bag, period.
