Mark II FVT, suggestion on stock for use with diopter rear sight

Recently received a Mark II FVT through CMP program. For BSA/Venture Crew training and competition. The flexi plastic stock has to go. The comb is not well matched for the rear diopter sight, esp for the little noggins of 14 year olds. Boyd's Pro Varmint looks promising; then I saw Boyd's new At-One stock. LOP and cheek adjustment with a nice rigid laminate stock. I have not had hands on either stock, so thought someone here who has set up an FVT for competition has done as far as stock selection.

Thanks.

The Boyds At-One would be a good option for various youth shooters given it's adjustment range and modular grip/forearm.

I'd probably go the cheap route and make a kydex adjustable cheek piece.
