x a billion on this.
The reason I said that was the guy was asking about gear. In gear, sumo is KING. You have a powerful pop from the gear, and the ROM is shortened.
Now keep in mind, it does bring its own challenges, but buckle down suck it up and you will overcome them.
Having said that, if you are competing raw, and your raw conventional is better than your raw sumo, then pull conventional. My raw conventional is far better at the moment than my raw sumo.
