A Bridgestone ballfitting team showed up at my club in mid-July. Besides balls they brought some irons with them.

I hit a 4i, 6i, and 8i in the J40 Dual-Pocket Cavity - shafted in PX 5.0. This model seemed to move through the ball quite well. I have the same shafts in Callaway X20 Tour, and the J40s seemed a bit livelier going through the turf.

I also hit a J40 Cavity Back 6i shafted in PX 5.5, and it seemed to feel about the same with a similar launch.

What is the difference supposed to be between the two models? Both are forged from 1020 steel, the CB has one degree higher loft in the upper irons, and just slight differences in bounce and offset.

Both are pegged for pro to mid-hdcp amateur golfers.

Any views on the performance difference between the models?

Focus, connect and follow through!

IMO, the dual-pocket is a bit more forgiving because of the pockets that are milled out of the cavity.  It moves the weighting a bit lower and to the outside, helping to minimize the effect of mishits.

Both are great irons, its more a matter what you prefer: a bit more feel or a bit more forgiveness.  Bridgestone really is one of the more underrated club companies out there.

    • I mean, if you like GZ, and would drink it more often during a round than water, then keep drinking that. If you walk 18 holes, on a hot summer day, and drink 2 20-oz waters or 4 20-oz GZ. You will benefit more from the 4 20-oz GZ because it's like 99.99% water, lol. Yea, if flavored water makes you drink more water, then that works better.  I would just monitor the salt intake relative to your own health. I am sure some people might have to be careful. GZ is 280 mg salt. So, 4 of those is over 1000 mg. It is over 4 hours. That is like half the daily recommended intake of salt. You are probably losing some of your salt reserves playing golf. Long winded way of saying, it depends on the person.   
    • My first few years playing golf, I'd take a 32 oz Gatorade (probably pre-zero;  almost certainly Gatorade Tiger when that was a thing) with me in my bag, but I'd otherwise take water (in about the volumes I take now).  From your post, it seems like going back to something like that might be a better idea for me -- primarily water (maybe with some fruit or mint leaves thrown in for flavor) and one bottle of sports drink, rather than a diluted sports drink across all I'm drinking?
    • Yesterday evening, I watched The Gentlemen, a Guy Ritchie film from 2019 that I evidently missed on first pass.  It's a par, but it's a par on one of those long par-4s where the par feels like a birdie. It's in a similar vein to some other movies like Lock Stock, Snatch, or Layer Cake (which was Vaughn, not Ritchie).  If you liked those, I think you'll like this.   A friend suggested it a few months ago, and I started it one night and couldn't finish because I was having trouble following.  In retrospect, that was an artifact of trying to watch the movie too late in the day.  I started the movie at the beginning earlier yesterday and got to enjoy the full thing very much, but unlike some other movies, I encourage anyone to watch this when they're awake enough to catch which characters are which.  In my case, watching with subtitles helped me understand what some characters were saying. 
    • Sweat contains about 800 to 1500 mg per liter. For me, about 45 minutes of moderately intense workout had me lose about 3-lbs of water weight. That is about 1-liter. Now, a thing you need consider how much salt you are getting from food. Humans have been perfectly fine eating food with extra salt added. Typically, people would get 500 to 1000 mg of salt just from eating whole foods. Most people eat processed foods, which have more salt. So, we probably are not salt deprived. We are constantly digesting food we eat and taking in that salt. Unless you are fasting, and working out, you probably are slowly getting salt back into your body.  I will say electrolyte powder is probably beneficial for people for intense training or long endurance activities in the perspective of improving fluid retention (helps in recovery) and preventing cramping. I would say, just drinking water is way more important in general. For something like running marathons, absolutely beneficial. For golf, this is a marginal benefit.  In terms of ideal electrolyte ratios, you want to be in the 2:1 to 4:1 sodium to potassium ratio. Though, I have also seen ratios closer to 20:1. This mechanism is vital for nerve impulses, cell volume control, and kidney functions. Potassium is essential for muscle contractions. Magnesium is good for muscles function as well.  Ultima Replenisher: 55mg salt, 250mg potassium, 100mg magnesium.  *Probably good for people who don't eat a lot of whole foods, or foods with a lot salt. Probably one in the same, lol.  LiquidIV: 500mg salt, 370mg potassium, no magnesium.  LMNT: 1000mg salt, 200mg potassium, 60mg magnesium. Skratch: 400mg salt, 50mg potassium, 50mg magnesium.  Transparent Labs: 500mg salt, 250mg potassium, 50mg magnesium. If I had to choose one, I would probably go with Skratch. My diet isn't 100% whole foods, so I get plenty of salt.  Note, if you have kidney issues, I would be wary of adding excessive salt. Salt can be very hard on the kidneys, and you might be negating the benefits of drinking that water. 
    • I ran the nutrients for Ultima Replenisher  by my friend who is nutritionist. She said it was a decent breakdown. So I bought the berry and lemonade packs at Target. Will give a try on the course today.
