Id go with a Mcmillian ADJ HTG or in you case since you dont want adjustable the regular HTG and probably even better for you since you want vertical grip would be the A3 which is the best stock out there I have used I like it way better than the A4 because its less weight and the foreend is not bulky.
The A4 is good if you plan on shooting of a rest more than out of position.
Manners makes some that are similar to the Mcmillians and a couple new thumbhole stocks that look like they would be a pleasure to shoot I have never used a manners but they get good reviews and are made pretty much out of the same stuff as Mcmillians.

They might have one in stock for your action so no long wait time.
I personally always get adjustable stocks I almost need to because my ideal LOP is longer than what most normal stocks are stock my neck is pretty long to so its rare that I find a non adjustable comb that can fit me good.
to me that feature is worth the little bit of extra weight.
you can keep down the weight by going with a lighter barrel for hunting you do not need it to be able to retain ultra tight groups during rapid sustained fire since you probably wont be doing that.
If you know who is going to build this rifle for you I suggest two things first make sure he is a good LR rifle builder the best you can find look to see who is making the rifles that are winning or consistently placing good at long range Comps in your state.
Second see what he has in his shop you might be able to try out several different stocks and find out what is ideal for your physical build and talk to him about the best barrel profile for intended use and Caliber.
