So i typically use hi lo, that's what i learned 2 years ago. Recently, i have been using wong halves when playing double deck. Are the index numbers just the same as hi lo? The only differences i see in wongs book are in higher counts and are minor anyway (ex stand on 16 v 8 hi lo at 7 halves at 8)

Seems like, since i have a ton of index numbers down from hi lo, that i could just easily play using halves. Im a little slower at keeping the count than at hi lo, but that's natural with 3 different card values.
