Then your programming sucks
My strategy for leg drive and keeping my ass on the bench is to put my feet so far back that when i use leg drive, i actively try to push my ass up off the bench, but its impossible to move.
I have it set up so it's above my hips but when I arch well below my chest.
Its definitely not going to hurt man.
Ive been using one the last few seesions, and will continue to use it indefinitely.
I think you may (not guaranteed) benefit from bring the bar out further when you unrack (depress the scapula more).
Had Minh and the guys at Elite start making me do this and I hit a comfortable rep PB despite only benching over 70% for 3 weeks since my shoulder injury.
As Stickler says too, slingshot won't hurt. If you're mainly doing raw the blue is best imo, particular for a sub-300lb bencher.
If you want more pop you can add reverse bands, or even loop a band around your elbow. Bit easier to do this than get less pop/support from the original slingshot lol
