Tell me how inaccurate my guesses are and explain the corrections!
More likely to be into a martial art:
ILE, SEE, EII, ILI, SEI, SLI, LSI
More likely to be into street fighting:
ESI
Would enjoy both (even if it's just watching one + only participating in the other):
EIE, ESE, IEE, LIE, LSE, SLE, IEI
Only watching any:
LII
