I've been using Ash Kev 16g x ZX Pro for around 5 years. I currently have approx 17 rackets with Ash Kev x ZX right now. I do agree that Ash Kev x 4G gives more control but it is more nuance that anything. It depends on how you prep the Ash Kev and ZX, then it is tension. I haven't used many multi crosses with Ash Kev so I am going to give Multifeel a whirl just for fun.
I only play one day a week with folks who think winning is more important than just getting out and having fun. And I am getting bored with that. At my age I just don't get it with the desire to "win" any more when just leaving the court vertically is a win

I normally play 5-6 days a week with an enormously wide variety of skill levels, from my weekly doubles night with a 30 yr D1 coach as my partner to hitting with "old" ladies my age to tune up their 3.0 doubles nite. Heck, even high school kids call me up to give them a hit. I really enjoy hitting with the college players but Covid has cut into that this year.
Covid has even cut into our informal "Smack Talk League." We had folk from 24-80 yrs old in that "league." Smack talk is required and graded, sort of like Olympic Figure Skating. We had a former hi speed Czech junior now a brilliant business woman, retired Uni Math prof, West Point grad former MI high school hall of fame tennis player, two guys from different eras who played for Hawaii Pacific, an engineer from Brazil, and an operations manager from S. Korea and the list goes on. Much laughter required and diversity in all aspects appreciated. One night I was playing and looked over the 4 nearby courts, mine and the 3 adjacent and said to myself, I am the only "old" white male out here, tennis is so fun. Reminded me of an earlier career where I would find myself in some odd place and have to shout out, "Anyone speak English?" Crazy as it may sound I found someone every time who could.
