Below is Titleist comment in regards to bounce:

We made the decision not to include the bounce angle because the modern sole design is so much more than just the bounce angle. Given that sole width, camber, grind, bounce as well as CG will all have an impact on how your irons move through the turf.it was no longer as relevant to list just the bounce.

So if someone is considering that model, and wants to change the loft they are in the dark as to what kind of bounce the club will ultimately have??

Unfortunately they haven't been giving bounce specs on the last couple iron releases. It seems when Vokey changed his measured degree of bounce I think back in the SM5 range they stopped advertising bounce in the irons as well.

Now this I'm not positive but for some reason it's stuck in mind....I believe Vokey said you can't really measure a rounded surface that's shaped differently. Since the grinds are shaped differently you can't really have a true comparative measure of degrees of bounce with varying grinds (or something along that line of thought....). Which kinda makes sense. With that I'm not sure how they quantify the wedge grinds but they found some formula to have a constant way to compare them now (I believe when they changed how they measure the labeled bounce varied slightly between the same grind going from SM5 to SM6). So with all that I believe that's they don't offer bounce specs in the irons, because the bounces between AP1/2/3 CB/MB/TMB are slightly different so with how they measure bounce it won't be an apples to apples comparison (make sense?).

But if some one knows for sure please correct me.

Makes sense but doesn't help when you are considering changing the loft of the irons, as every degree of loft also changes the bounce by that same amount. So if the bounce is very low, and you strengthen the loft, you could end up with a negative bounce club.

Should be listed on web site in specs

Though they don't list bounce in the specs, I seem to remember my previous set of AP2s (712s) were about 8 or 9* of bounce in the shorter irons. I think a little less in the longer irons. Never really thought about it again when I got my most recent set of AP2s (716s) or my newer AP3s. Nor has it ever crossed my mind when making a swing with either my AP2s or AP3s. I play a 50.08 SM6 F grind wedge, a 54.10 S grind and a 58.12 K grind. Not sure what I'll do yet about switching to the SM7s, which I plan to do this month, but for now the bounce on each of my wedges seems to work perfectly for me. My guess is that the AP3s are somewhere between 7 and 10 bounce, from 6i to GW, but, don't know for certain.

As others have stated, there is no need to be concerned about the bounce on these particular clubs. Focus on loft and lie angle. My recommendation is to have them checked at a club repair shop after playing with them for 10 - 12 rounds, then rechecked every 8 - 10 months based on how often you play. Enjoy your new equipment.

If Vokey wedges show bounce (and it matters), then the new AP3 irons show list bounce also, just as it has been in the past. It is not rocket science.

Has this information ever been rectified. It is much needed for proper fitting.

I personally would prefer that Titleist had continued to share measured bounce angles for all their clubs, not withstanding the fact that a single "bounce angle" number only tells you a very limited amount about how the club will play. Sole width, camber, leading edge shape (straight or curved), leading edge sharpness, all these matter a lot in addition to measured bounce.

That said, in the end even back when they still had "9 degrees", "5 degrees" and so forth listed on the spec sheet the only way I've ever found out whether a set of irons will work is to hit them off actual turf in actual playing conditions for myself. So it all works out about the same I guess. I just can't see the harm in having that one little bit of numeric information published.

It's funny how when publications or advertisements or other golfers talk about "forgiveness" in irons they totally mean how far the ball goes on a high toe hit or how easy it is to elevate the ball with low clubhead speed. For me the single most important kind of "forgiveness" an iron can have is how it handles turf interaction with my typical good and bad swings on my home golf course.

If Titleist could build an MB iron with the same MOI and COG as a 718 AP1 it still wouldn't be a club I could use. That skinny sole and leading edge shape would kill me every time I got a little steep-and-deep at impact.
