Spinning tops (Beyblades)

GarIT

So my brother plays with spinning tops called Beyblades and he asked me to help him win more often. To win he needs his Bey to spin for longer than any of the others while being hit by the others.

The first thing I think should be done is minimise the contact area with the ground.

Am I right in thinking that when using a heavier Bey it would start slower but spin for longer than a ligher Bay given the same ammount of force is applied?

I presume another advantage of it being heavy is it would have more stability over one that is lighter when they collide with each other.

Some of them can have jagged edges and/or bits that stick out and some can be more smooth. Would I be right in thinking that a perfectly circular one would face less wind resistance and spin for longer?

I used to play with them when I was younger and adding more weight or extra metal rings seemed to do the job

I think its similar to a train, a big heavy train takes longer to stop than a light passenger train because F=ma

Adding weight helps a lot, but keep the following in mind:
-Adding it further from the centre helps more.
-You'll have to add it evenly, or it'll be unstable.

A circular one will spin for a very long time, but won't really do a whole lot to the others. It seems like it'd be the best tactic, but I think it'd remove the fun from them to an extent. Wind resistance won't be a big issue if it's spinning fairly quick.

If you've added a bit more weight, the best thing to do is make that thing you pull longer; a longer one gives you a lot more speed.

The faster you get the top spinning for any given weight the longer it will stay spinning and if another top hits off it and the less likely it is to be knocked from its position or veer off course.

The heavier you make the top then the harder it might be to set it spinning. A lighter top which is spinning faster can possibly do the same job as a heavy top spinning slower.
