Spiral cut vs. Standard diff gears

[simplechamp]

So it's not like spiral cut is the new big thing making standard ring and pinion gears obsolete... each has advantages and disadvantages that only the individual user can decide what works better for them.

The reason I asked is because I just bought the V3 hybrid diff kits for my E-revo, then I started looking at diffs with spiral cut gears and thought "great, now I need to spend more money to convert the diffs to spiral gears" but I think that would be overboard for now. Haven't even got the E-revo yet and I'm already going broke!
