what's the advantage using titanium spokes? obviously they are light, but which are stronger? which are more resistant to snapping? i tend to snap spokes on the rear wheel drive side of course. i tried regular spokes, & stainless, so far the stainless hold up much better it seems but i never tried titanium. is titanium available in standard sizes? i have 2 old 27 x 1 1/4" rims/ 36 spokes.....
