Not sure if you only wanted IN people to reply but I'm going to anyway.
DEFINITELY STAY AWAY FROM METAL SPUR GEARS ON THE SLASH!!!
If you set your mesh right you will not chew through many plastic spurs and when you do its far cheaper to buy a $3 gear and undo 5 screws and 1 nut to change as opposed to ripping your tranny apart to replace a blown diff gear or otherwise. You always need a weak point on any vehicle and its best to have the spur be it. I promise.
As for gearing 25/90 is a little odd but I wouldn't say overgeared. What size track?
What you may want to look into doing is changing to 32P gears. The Jato/Revo spur gears are a direct bolt on. The bigger teeth allow for less stripping and more gear choices. It also tends to run a tad warmer though so be careful. To answer your last question, Lipos are ALWAYS better than Nimh batteries. For racing the first 2 or 3 laps you may have an edge running 7 cell Nimh (if your track allows it) but in the end the lipo will hold its power much better and be faster.
hope this helps.

Size of track is critical to proper gearing. I run three different tracks and depending on which one (they are all different sizes) I run 18, 21, or 23 pinion with a 90 spur. 18 is for track that has a lot of short runs and the 23 for a track with a long straight and not too many turns. The 21 is for a track that is a combo of the other two.

I run 19t on stock 86 spur in indiana. I would run 20t for a 90 spur.
