Stronger so less chance of break.
None that I can see
I bought my Halo B used, and the guy never have the drive cone put in, so I had the brand new cone put in. It seems stronger and tougher. It's also white so I guess if you had some paintballs breaking in your hopper you could see it easier.
If you want your drive cone to be stronger and stand less chance of breaking then this is a great upgrade.
