I still love shooting a flatter trajectory. I'm never going to purposely add more weight just for the sake of adding more weight. The only reason I would add more weight would be because of me going with a tougher shaft, like the CT Rhinos, for something like pig hunting, so they won't be as apt to break. If I am in a situation where my shots will be short, I usually go with the tougher Rhinos, since there is no disadvantage to shooting slower at close range. But for longer range situations, I'm still going to go with my lighter shafts, like the Victory RIP XV's or CT Cheetahs. Those lighter shafts give me good speed and with 125 grain broadheads and also give me an FOC with good accuracy.
That said, I have recently said goodbye to the Omen UF and Full Throttle FT cams. I get great speed out of PSE GX cams with a much, much more hunter friendly draw and let-off. If the UF cams didn't have the hump, and felt like the GX cams, I would still be shooting them, probably til the day I die. I'm so glad I tried the GX cams on the center pull risers, despite so many saying it wouldn't work, they work fantastic! That was the best move I have ever made, other than changing from feathers and vanes to FOBs. It's going to hurt a little to see my Omens go because if the incredible accuracy I got with those bows, but I sure won't miss the hump & dump.
My light arrows usually run close the 350 grains and my heavier ones usually run around 400, but with less FOC. I don't have a habit of weighing my arrows. I also don't have a habit of speed testing my arrows. I owned a Chrono for two years before I ever used it. I just shoot a fast bow so I don't have to worry about arrow weight. I definitely would NOT want to shoot a slow bow.
