I don't even look at speed. In general I want my 4 best offensive players in the top 4 spots, ideally looking something like this:
1: High OBP, low SLG
2: High OBP, high SLG
3: Low OBP, high SLG
4: High OBP, high SLG
5-8: descending order of OBP
That's just a general guideline. I deviate from that in many different ways. Will sometimes adjust a player up or down a slot based on extreme PA differences. Will sometimes bat a low PA, high OBP player 9th and put the pitcher in the 8 slot. etc.
