objectives?
i play speed freeks, and i LOVE them, but i play them because they're hilarious, not because they're effective, my infantry horde orcs are for that. speed freeks can win, but you need lots and lots of trukks, which = lots and lots of $. IMHO, it all comes down to what you want to get out of your list. if you want effectiveness, and want to play orcs, go with a list based in infantry (shoota and slugga boyz and flash gitz) with some back up fire power (looted basilisk works wonders in that capacity) if you want to be the comic relief of the battlefield, have alot of fun, and occasionally surprise the enemy with a win, go for speed freeks. they can still be deadly if you don't want to spend the cash on trukks, through conversion, but one way or another, you need those wartukks, and lots of them to be effective as speed freeks, so again, i'd examine your wishes for the list first. i hope this helped, good luck Waaaaaaaaaaaaagh!
