Some may wonder about the trajectory of these heavy Red Balau wood arrows (actually were jokingly refered to as "telegraph poles" at a shoot I went to once Sam), but in my experience I've certainly never found trajectory to be an issue.
Even when everything is in my favor, I still like to limit my shots on game to a maximum of about 25m, but I way prefer getting in to halitosis range anyway, so trajectory doesn't seem to matter much then
These heavy arrows do seem to shoot fine for me out to 30-35m when bashing pine cones or a tennis ball around the paddock though.
I've never been remotely worried about the FOC of these heavies either. Just try for as perfect tuning as possible, and work hard on putting a good properly sharp broadhead in the right place, and I know penetration will certainly be more than just adequate
All my arrow set-ups are 29" VON to BOP. Running 105-110# shafts with 235 grains up the sharp end for the 75lb, and 85-90# shafts with 190 grains on the front for my 65lb.
Bows sure are quiet too.
Best
