Hi Chris,  You should be able to call the Golfsmith phone line and order the 50.12, which is only offered in the F grind (full sole grind).  On the 56° wedge, that is offered in the 56.10 S grind or if you are looking for more bounce, it is offered in a 56.14 F grind.  Again, that can be ordered by calling Golfsmith. They may not stock it in the store, but it can be ordered. 

Chris,

Thank you for your question.

Currently, the 50.08 is available in the F grind, or the TVD-M through the WedgeWorks Exclusive line.

As for the 56, we currently offer this loft in 3 bounce/grind configurations through the SM5 line. These options are the 56.10 M, 56.10 S and the 54.14. We also offer the 56 degree in a 12 degree bounce in the TVD-M and TVD -K line through WedgeWorks Exclusives. If you are interested in the S grind, and wish to have the 12 degree bounce, we do also offer options to adjust loft 1 degree, allowing you to take a 54.10 S and bending it 1 degree weak to get to a 55.11 S. 

Please visit http://www.vokey.com/wedge-selection/wedge-selection-guide.aspx for more information of current offerings both through Titleist and Vokey WedgeWorks.

We highly recommend visiting your local certified Titleist Fitter to be properly fit for wedges and other clubs in your bag. Your local Titleist fitter can be found using the Golf Shop Locator at Titleist.com

Thank you
