Ultimate Team: First Fighter Type

It seems to me at least that when you create a new fighter at 65 overall they're pretty bad in general.

Is there any fighter style, i.e. boxer or muay thai, that is good for just grinding out those initial wins until you can afford some packs?

Also is there a weight class you'd suggest? I enjoy the idea of submissions (even though I'm bad at them still) so chose heavyweight to try to create a kind od Frank Mir or Josh Barnett fighter. Just not having much success with this but this may be going for submissions and not the weight class.

Thanks for any advice you can give :)
