Choosing PowerBlock dumbbells

Hello! I need help choosing a set of dumbbells from the PowerBlock website. I want to take advantage of their Black Friday sale! I currently only own 3 sets of dumbbells: 5 lbs, 8 lbs, and 10 lbs. I have felt like I need heavier ones for exercises like deadlifts but have never tried lifting heavier than 10 lbs. The Pro 50 looks nice but I can’t imagine lifting 50 lbs! I think the Sport 24 is probably more realistic for my current fitness level. Does anyone know how heavy Kelli usually lifts when doing deadlifts? Thank you!
