I have 7 British guns 4 in BQ1. All are shooters. I am tall and these guns had short stocks originally. Here is how I have handled the short stock issue:

2 restocked (orig stocks <13)
3 ebony extensions (orig stocks +/-14)
2 walnut extensions (same)
LOP is 15 3/8.

Personally I have no concerns with well made extensions. I prefer ebony to walnut and prefer wood to pads. I am underwater on one restock and am probably at market on the other one. I have acquired the guns to hunt and shoot, so the extensions do not bother me as they allow me to use the guns as intended. I have previously posted a couple pictures of my extensions.
