You're more of a fighter than probably most of us on this forum, so keep at it. If you're doing it to stay in shape and keep strong, or simply because you enjoy it, then honestly it won't matter if you're training in multiple arts. I would caution though about overdoing it...the body needs time to rest, so balance young grasshopper. But if you're training for skill, I tend to be one of those guys who finds one thing and sticks with it. If for no other reason, the law of diminishing returns. There's only so many hours in the day and so many days in the week, and you only have much energy. I personally find it better to be good at one thing than mediocre in a few things.
