The best flight I've found came from Slick Trick 100 gr. Mags, and 100 gr. Shuttle T-Locks. The T-locks out penetrate the Slicks Tricks by a bit as well. Old g/f got a complete pass through, quartering away, with 100 gr. T-Locks shooting at 48# 25 inch draw. Roughly 385 gr. arrow, so it was probably only going about 230 fps or so. Broke 2 ribs going in, 2 coming out, and left a massive exit hole. Once I get everything fine tuned, I'll be using those T-locks myself.
