For Drivers, there is only Titleist Sure-fit hosel, and the LH setting for C1 is +1.5 degrees loft, -.75 degrees lie. An aftermarket adapter would be expected to follow that convention. D4 would still be the standard setting.

I'm a lefty also. Hope this pic helps. I keep it on my phone for any adjustments I may make.

Are these adjustments for LH Driver, woods & hybrids?

C1 is most fade (+1.5* more loft) and flat (-.75*)
Just search Titleist 913 fitting chart left hand and you can see all the LH adjustments. Hope this helps.

I have attached and image of the chart I found. Hope this helps.

No, C1 setting for a lefty is +1.5 and more fade. The standard setting for a lefty is D4. You can always Google 913 performance guide left hand.

im new to the ts2. what does setting a1 signify on a left handed ts2 driver. thank you.

All the Titleist metal woods from 910 to now use the Sure-fit hosel adaptor and the settings are still the same in the chart above, A1 LH is +0.75 degrees of loft and +0.75 degrees of lie. So a 10.5 degree TS2 will now be 11.25 degrees of loft. The face also closes a small amount and will increase a tendency to draw (or decrease a tendency to a fade).

Since the 816 release, the hybrids only differ in that the loft changes are +/- 1 degree.

Anyone know how to replace a tip? Looking at swapping shafts from a 910h to a 913h head and they have different sized adapters.

A decent pro shop should be able to swap adapters, with an adapter designed for 913 - TSi hybrids.
910 hybrids and fairways are the orphaned step children. The adapters are not compatible with all the later versions.
