10 rounds.

Helenius pts. Cooper was dangerous but he usually didn't beat the higher level fighters.

Helenius stops Cooper within six to eight rounds. The Finn's advantages in height, reach, and long-range punching power (especially left-hooks to the body) are too much for Bert.

Cooper was an exceptionally rugged fighter. Very few heavyweights could KO Bert during his prime. Helenius is one of those few who would get the job done.

On the subject of Cooper, it's a shame he didn't remain at cruiserweight, where he had the potential to be a world champion. I guess Bert moved up to heavyweight because he got lazy and let his weight balloon.

Helenius would stop Smokin Bert in 6 rounds.

I'd take Helenius as well.

Helenius TKO 9

I’d pick Cooper to smoke him.
