Okay, here's the story. I am replacing a 913H 19*, with a new 816H1. It will be the 3rd club down in my bag after my 915D2 Driver and 915F "weak" 3W (16.5*). My 4th club is presently a 23*H, which will shortly be replaced with a new 816H2 23*. But first I have to decide on which hybrid I should put in the 3-slot. It will be either a 816H1 19* or an 816H1 21*. I am just not sure which I should choose. I have recently hit them both and like them both, though not on a monitor. I was also fitted on a Trackman right after they were released. However, at the time of the fitting, I had just hit a ton of balls warming up and being fit for my new AP2/AP1 combo set, trying many different shaft combinations, and frankly, wasn't really swinging my best by the time I got to the hybrids. As mentioned, I have since hit the hybrids with better results, but not in a fitting. I am not paying for another fitting. I am confident with the shafts based on other Titleist clubs I have played and been fit for with virtually the same shaft. (Diamana 2015 blue blueboard vs 2016 silver blueboard.) So I really don't feel the need to be fit further.
My concern is whether I should go with the new 816H1 19* or 21*. The new 816H 19* is now considered a 2H, whereas the 913H 19* was considered a 3H. That means a 1/2" longer shaft should be standard in the new 19 than was in my old 913H 19, right? In my mind, that makes it a touch more difficult to make a pure strike every time than it would be with a 1/2" shorter shaft as would be in the 21*, am I right? So, the question really is, with all the new technology like a relieved leading edge, Active Recoil Channel and thinner face being built into the new 816Hs, should I expect to gain some yardage on pure contact hits with the new 816 21* 3H vs the old 913 19* 3H? Or would it make sense to go with the new 816 19* 2H if I'm looking for 5, max 10 more yards out of that slot in my bag?
For the record, I play regular flex shafts, am now 60 yrs old (ouch) and usually carry a GHIN somewhere between 8 and 10.5, if you think any of that matters.
