believe the world record strict curl in my weight division is a buck 30 something
maybe I should gun for that record too
Are you training for size or strength?
I ask because you seem to be obsessed with both how much you lift and how much you want to weigh, and sometimes from my observation those 2 goals can conflict with some people ie some people can gain size by training for strength, while others(most likely you) need to drop the ego and weight and feel the muscle work through a full range of motion on most movements.
Just an observation since you are looking at how much you lift on an iso movement like db preachers
PS those dumbells in the gironda pic being lifted by actor and real life tough guy Bob Tessier are Vince's fake wooden ones, much like the fabled fake 45's at golds
