I split the difference, using 75s at race pace to train for the 400/500 free.
I often do 75s as well. 100s are just a bit too long to hold 500 pace for very many reps. 50s and 75s are doable.50's I find too easy. I can cruise the first 25 off the fresh rest, blast a strong turn, and maybe only "feel the burn" for the last 10-12 strokes.
What amount of rest are you taking? If I try to hold a fast pace (~200 pace) on a sendoff where I get 20 seconds rest, it doesn't take long before the pain starts to set in. I can maybe do a dozen or so and then the burn gets pretty dang intense.
