I have a "lightning bolt" type wraparound bridge on a sg jr. The intonation is ok-ish, but it could be a tiny bit better. As well I need to get used to palm mutting on it as I was always used to standard tunematic bridges. My conserns are that if I upgrade a different wraparound these small issues would get eliminated, but on the other hand Im thinking that I might loose sustain because adjustable tailpieces has more parts in it and are a bit fidlier than lightning bolt type as it is directly on tention going to the body. As well this upgrade isnt cheap. Is it worth it? And which wraparound would you choose?
