Almost the same feeling. I have two rear diff and one is (Kyosho)#30000 for high traction track. Another is (Kyosho)#20000 for mid traction track. With sandy track I will use #10000 or #8000.
I have both front diff/spool/1-way. Last Sunday race I have tested spool. It is very good for bumpy track. Slower turn in so you need to set the front spring softer and less caster. Also maybe narrow the width. It performed better than what I thought.
