After doing some more tests today I'm going to have to go with the 10 point profit target strategy.  Since I can't trade full time (yet) I looked at what happens to each of the two strategies when they are traded on and off, as in, one week on, one week off (as I'll be doing).  The 8 point trailing stop strategy suffers quite a bit, since a relatively small number of the trades account for a large share of the gains, whereas using a 10 point profit target strategy means the profits are spread more evenly out accross all the trades, meaning less impact from on-off trading.
