Both of you! Start low!
Seriously, 10x3 with 80% of your max is a lot of volume and a lot of weight. It has made me more sore than any other benching program I have done before.
If you are struggling your very first week at these weights than take it down a few plates.
When I started my max must have been around 315 and I used 250. It was tough but I did not have any super slow reps. Weaver, try 240 and T-Cock maybe 230?
Nice Squats BTW, 430 is a weight I have never touched on squats.
