It's hard to majorly mess LTEs up aside from turning them into something else or dropping the weight on yourself. I would still setup like you do for a bench press (get shoulder blades pinned and tight against the bench). Your arc of the barbell is at times a bit far away from the top of your head. Try and keep the bar a bit more consistently close to your head as it passes. Getting it locked out over you when it is heavy can be a challenge. You can clean it up to a pressing position, then sit on the bench, then lay back on the bench while keeping it pinned to your chest. You can then bench press it straight up.
