Not planning to change string material permanently, just shoot maybe a dozen or two arrows with it to see how the sound changes between small, medium, and high brace heights.I wouldn't recommend shooting any *x* string material off a recurve these days. Several manufacturers, including Hoyt (in a roundabout way), Border and Uukha advise against as their properties are not good for limbs. They were designed for compounds that are permanently strung, and whose limbs are short, thick, and wide, with a different construction, so take sudden stops much better. Yes, the material is a tiny bit faster, but much harder on the limbs and has been attributed to failures.
For a basic rod experiment. Take all your rods off and shoot with just you sight. It's an illuminating experience, not just from the noise point of view.
I've tried (and recorded) pretty much all possible combinations of weights and/or stabilisers and/or dampers. Taping a laser pointer to the sight works nicely to see what's going on. Tried scoring once with the stabilisers switched out for just a barebow weight, the loss in accuracy was only about 20 points on a Portsmouth, despite the high frequency movement of the sight. With more practice I expect the difference would be smaller.
