The trap bar, normally reserved for low-body work, actually works great for pressing exercises.
- The handle angle (neutral) is better for your shoulders and elbows if you have issues in those areas. This is especially true with the versatile Dead-Squat Bar; https://biotest.t-nation.com/products/dead-squat-bar it's handle is slightly angled to match your natural hand/wrist position.
- Your head doesn't get in the way. This make for a very natural press with little to no leaning back or weird neck angles.
Try an overhead trap bar press using the dead-stop style. Start with the bar on the pins in a power rack and do each rep from a dead stop – no bouncing at the bottom.
The pins should be set anywhere from your traps to the top of your head, depending on your shoulder mobility and how you like doing your overhead presses.
