(It's including in the class price regardless)
If gear rental is included in the price of the class (as mine was also) you'd be stupid not to use their gear. Why? Because it gives you an idea of how that kind of gear (whatever it is) works. Its a baseline for your final purchase choice. Besides, you may find you like what they are using. No matter what everyone on this board says, and there are a lot of gear snobs on this board, you and only you have to try it and like it first and foremost. Don't go by word of mouth only. There is nothing wrong with any of the gear that exists today. It all has its pros and cons. You can take a 4x4 duelly to the track and slalom it, but it just isn't a Corvette. Similarly you can tow a 10000lb boat with a Ferrari, but it just isn't a SuperDutyF350.
