Quick draft question

Got a quick question. I am in a keeper league. I decide to keep Lamar Jackson in the 15th round. I have the 8th pick in the draft in an 8 team league. I got offered the 4th spot in the draft for the 8th do I switch draft positions! I kind of like picking twice at the turn.

Feel like I have a better chance of getting Clyde Edwards-Helaire and another top back at the turn.

Or do I go to the 4th pick and have a better chance at getting Barkley

If It’s just a 1 keeper league, I’d switch to the 4th position and guarantee yourself a higher 1srt round pick (likely RB).
