Floxter, et al -n
A 10" bh may have been the norm, but the PMs, at least mine, [1 70"/#35, 1 66"/#41, 1 62"(PM Super Hunter)/#48, and 1 TD PM 67"/#43; 65"/#61; 67"/#81,] really like the lower brace heights. It's free speed, and I've seen no lose in stability. Yes, I measure with a square to the deepest cut in the grip (throat).
The #35 with an 1816 is around 180 fps. I generally don't worry about speed, but as I said, it free, had haven't seen any down side. Besides, the damn thing looks better with a lower brace height,
Viper out.
