If all you need is 675, I would definately start there. You know I'm not a full power guy, so I'm not savvy on how much skwatts effect bench strength. If it was bench only, I'd say go for it with your training #'s, but it's not. You can always go up if you have problems touching,but can't go down if you have lockout problems.
