for every 1 tooth in the front it is equivalent to almost 3 in the rear.  

For every 1 tooth in the front down you go you will raise your RPM by 1000 to maintain the same speed.  soooo

if stock gears you could be in 1st gear at 6000rpm and do 20mph
if you go -1 in front in 1st gear at 7000rmp you will go 20mph

that's about the easiest i can explain it. I would only suggest doing made -1 / +2 or +3.   Start with the front sprocket at -1, you wont have to change your chain and will get a feel for the difference and see if you like it.
