THS3491

THS3491 looks like an interesting op-amp for distribution amplifiers and in general for LF/HF work. However it turns out it is a bit finicky about the feedback resistors (high resistance values are stable but noisy, low values would give low noise but might be unstable). We're sticking with LMH6702 for now..
