That is about 5 yards per degree....seems normal to me, but I am not an expert...my five iron is set at (714 AP2S) 26* and my irons are gaped at 3* except in the wedges and they are 4*.  I am playing my 713h 24* at 23.5, 816H1 19 @ 20.0* and a 915H2 18* @ 17.25*......you are a bit longer than I am.....but I love those Titleist hybrids.....all of us are not the same...it is just a matter of what works and what feels comfortable for the conditions.  Give it a try at 23 and see how you like it...... 

Hey Chuck, was wondering how you like playing the 19* set at 20*. I think it is a longer shaft than the 19* 913H I am presently gaming.

I am torn as to whether to go with a 19* or 21* H1 to replace my 913H. It was designated as a 3H, but now the new 21* 816  is called a 3H and the 19 is a 2H. That would suggest the shaft on the 816 21 is the same length as the 19* 913 and the 19* 816 is a half inch longer. So you are playing your 19* set to 20* as opposed to a 21* set at 20* using an 816 21* set stronger to 20*. My thinking is that the 21* length shaft might be a little easier to make center contact than the longer 19* length shaft. My concern is that there might be a difference in distance if they are both set at 20*. Ideally I would like a few more yards out of that club slot.

Does anyone else have an opinion on 816H 21* versus 19*, both set at 20*? IMO if both are hit dead nuts, the 19 set to 20 should garner more distance than the 21 set to 20, simply due to more clubhead speed through the ball with a longer shaft. But, how MUCH more distance is the question?

FYI, my next hybrid in line is an 816H2 23*.

I am not a long hitter of the ball at 69.  I hit that club around 185 consistently and am happy with it.  I like the high flight and how it sets on the green.   I go practice with my hybrids and the setting and if they hit my targets, then I am happy and throw them in the bag.  I actually have four hybrids, but only carry three (actually lofts:  913h 17*,  915h2 18*, 816H1 19*, 913h 24*).     

just got new 716 AP1's my self and a new H1 816 in 21* so far my gapping is good my bag goes:

915 D2, 915 3-wood, 915 5-wood, 816H1 21*, 5-w2, vokey 58* and a Scotty GoLo

same set up for me but so far gapping is good but living in Ky its real wet and soft so once it dry's up and I can pinch the ball nicely it may change
