Want to thank everyone for their comments and advice. Seems to be the consensus that the disk is the better choice if given the option. We currently run the Hilliard Flame with Bully conversion. Thanks Mike for your offer and advice, unfortunately, it made more sense for me to go with a Bully since I already have the drivers. Brian Carlson, it was awesome talking with you and your wife, Sarah, really appreciate the help and knowledge you gave. It is a pleasure to deal with you guys. People like Mike and the Carlsons help make kart racing enjoyable for us newbies, lol. Thanks again everyone!
