We did place an order on those plastic tanks and new compressor to save weight, but we would like to be a bit safer, you know just in case

Okay, gotcha. Then if you're that close on weight and already making some other amends, trying to switch those sprockets out does seem reasonable (and I'm impressed/surprised it adds up to 2 pounds, that's pretty significant!). The new compressor and tanks really do help by a lot though (likely more than one pound, quite possibly even off-setting the three that you are over). However, making yourself a pound or so underweight couldn't hurt, right? Ya never know what will come up during competition.
