I'm no expert but have made the same transition recently...

I think the additional weight benefits running in grass also, it allows momentum to pull you through divets, ruts etc that would stop a 1/10 almost dead. I ran a 6S G3 6500 in my 8ight-T last weekend & the additional weight made it almost 1:1 car like in it's handling, it didn't get upset by lumps & bumps that would normally have it spearing off in all directions

If it runs well over grass, it'll run well anywhere!
