Need to drop poundage on my Matthews LX bow

You may be droping the poundage too low. If to loosen the limb bolts too much, you could damage the bow and or have a limb slip out of the limb pocket. You shouldn't drop below 60 lbs if you have 60-70 lb limbs on the bow. If you truly want to drop to 55 lbs, then the safe thing to do is to buy new limbs that are rated for 50-60 lbs.
 
One more thing...Before you start turning the screws tighten the bolt all the way in on both limbs. Then turn it down one turn at a time on both bolts. On my Mathews there are indentations on the bolts for alignment and measurement. Mathews says that one turn equals 2-4 pounds but I have found that it equals 2 to 2.5 pounds per turn. So four turns out should be around 8 to 10 pounds. You want to make sure that the bolts are turned out the same amount each. I did one at a time to lower mine to 65.

You should probably take it to an archery shop so that they can put it in a vise and do it for you.
 
You may or may not be overspined at the lower draw weight. Just check the charts for the type arrow you are using. With carbons, there is a pretty wide range of draw weights for a given arrow size and length, so you are likely to be OK. If you are overspined at the lower draw weight and don't want to buy new arrows, you could go to a heaver point to decrease the spine. Of course you will end up with a heavier arrow and lower velocity - if you care about that.

String and cable condition and the amount of twist of both can factor into poundage, which is why they say 2-4, as not all set-ups are the same. Not all Matthews bows will be 2 -2.5 lbs per turn of the bolt.
As strings and cables age (especially the cable), they stretch, leading to a decrease in draw poundage. This can be corrected by taking the string/cable off (using a press) and giving them a few extra twists to tighten them back up a bit. I know many people who have been upset about a new bow not meeting the max draw weight of the limbs, when it's not the limbs or bow, but just the string and cables not being of the correct length b/c the string/cable are not correctly twisted.
With that said, don't go and try twisting your cables to make a 70 lb bow into a 75-80lb bow, as you're only asking for trouble. Never exceed or fall below the rating of your limbs.
