So I built 3 wood to standard length using a UFW head and a grafalloy-prolite-35 shaft. I used a tour velvet midsize grip and installed a reminder rib. This club is awesome. For me it is finding a ton of fairways and carrying about 240 give or take with a straight to slight draw ball flight.
It was time for new grips on my irons so I decided to use the same midsize tour velvet and reminder rib on my irons. The irons are mizunos JPX825 pro’s, the shafts are KBS Tour FST. They had the original grips on them, I would assume standard size with a .580 core
Prior to the grip change I had been fighting a hook. Once the new grips are installed I am fighting a terrible slice that I cant get to go away. Even the best shots are still fading some. Any change its the equipment change and not me? Swing weight issue maybe?
Difficult to say without seeing you hit shots, but the midsize will weigh more and result in a lighter swing weight. Funny thing what subtle changes in the feel of a club can cause us to do. Assuming the “rib” is properly placed and not in a position that could effect how you grip the club, I might start with adding a little lead tape to one of the clubs to get the swing weight back up and see if that makes a difference. If the midsize fits you, then it should work for all your clubs. In rare cases I have seen players have one size on their woods and another size on their irons. Just works for them, the way they swing and the way they want those particular clubs to feel.
