hmmmm ... I would probably give to Gunter (Dallas has a smaller waist/better taper, Gunter has a better back) otherwise they match up pretty evenly (both carry tons of mass) -/as you said Gunter had the better conditioning ....Dallas has the potential to be good , I mean like really good!
Dallas has much better flow/symmetry than Gunther. He is so young that in time, I think his back will be on par with Big Ramy.
Great posts - or maybe I should say, that's also how I see it.
I think it's safe to say that Dallas is ahead of Gunter, when Gunter was the same age. Dallas may burn out yet though, as a result of that pace. It will be interesting to see if he can bring his back up. Ultimately genetics factor in, and there is only so much any person can do. Maybe the key will be conditioning and posing improvements, to better show the world what he has, flaws included. I hope Dallas has the right people in his corner giving him the right advice.
