Note that due to the mathematics of dice rolls, the difference between 1d8 and 2d4 is more than just a higher minimum value on the 2d4 roll.  With the d8, you have an equal chance of getting, say, a 5 and an 8.  On the other hand, the 2d4 roll is statistically more likely to lead to a total value of 5 than a total value of 8.  This is most easily explained with a table of the possible outcomes:
