I've been doing trap bar deadlifts for the past several months and am ready to get back into competitive style deadlifts. I've always used the conventional version in the past but have had people try to convince me to switch to sumo, citing reasons like better leverage, safer for the lower back, etc.

When I've dabbled with sumo in the past, I have noticed I lift more conventionally. However, it was not a big discrepancy, and that may be partially explained by the fact that I had not trained much in sumo style.

I am six feet tall with long limbs, which seem to favor the conventional form. However, I also have a tendency to round my upper back on limit lifts, which may lead to back problems down the road. (I don't round my back at all when pulling sumo.)

Any experiences and/or observations regarding how to select deadlift form would be appreciated. Thanks.
