Barbells are ideal, though 300 is a little light. ;-)

What are the advantages of machines again?
They do have some advantages. I wouldn't want to try doing 10 squats
as fast as I can with as heavy a weight as I can, because about one
time in five I'd screw up, squat down too fast, not be able to stop
myself in time, and I'd probably get a back injury.
Well, that's one reason. I wouldn't want to do 10 rep sets either. I
wouldn't squat fast either.

Avoiding injury is good; what's the point of the fast 10-rep set?
Seems to work better for helping me get a boat moving fast. Power = force x
velocity, the higher you try to make force go the more inefficient you are
in a rowing boat, so you need to be able to move yourself quickly. But you
have to be able to provide significant forces to move quickly, in particular
you need to be able to accelerate the boat through the finish of the stroke
to minimise fluid drag on the recovery. I find that just going for strength
(steadier pace, heavier, probably less reps) doesn't get me that; I can
accelerate the boat fine through the first bit of the drive but as it speeds
up towards the finish I'm chasing it and I can't keep it accelerating.
10 strokes is about the length of a typical start, hence 10 reps. Again,
seems to work for me.
IMO, the most important weights exercises for rowing are deadlift, leg
press, bent-over dumbbell row, full squats, in that order.
