You know something I find amusing...
I am right handed. But, I am largely ambidextrous when it comes to anything other than writing..I can play the guitar with both hands for example.
BUT, when I do uni presses, my right side is ALWAYS the weaker one - even though the side I use largely is my right side.
Just some personal quirks
Good job on the 70 lbs. Damn that's shit heavy for a uni press!
