Hey Towton,
How are you?
If you are not sure what discipline to train in you could attend a Mixed Martial Arts class, you might enjoy that, and further than that it might actually give you a better insight into which single discipline you enjoy.
Check out Forge MMA in Sheffield, they do open mat sessions, Brazilian Jiu Jitsu (Ground Game based) and Mixed Martial Arts classes through the week. I did a months training there and loved it.
Hope that helps,
Bradwell.
