A TCD sounds like it would be optimal for your position. So low carb /ketogenic with the exception of pre and/or postworkout. I'm not sure what your diet setup looks like currently but you could bump up the carbs postworkout, and potentially preworkout.
Another option would be a Paleo Style Diet. You can get a good amount of carbs in from fruit, and I have found that helps my strength a lot and fruit tends not to affect me like oats & sweet potatoes do in regards to digestion.
Hope that helps.
