Don't know about the Holymoto brace but I bought the Trask it's US machined, boxed steel and weighs 2 Lb ! Super strong but it did need some dremel tooling to clearance an area around one of the main bolt bosses. Got it for $ 197 ( half price ) off e bay. Fitzgerald has a nice pan and his girdle is aluminum - probably a lot lighter but I don't know how strong compared to the steel - also you might want to pin your bearings as cheap insurance, he does that as well.
