As a high school student, I'm really not sure if this is a good idea or not. I know it is not at all necessary, but I've been saving up plenty of money, and I thought it might be a cool thing to do for my Kolstein Fendt.
To my understanding, the four types of C-extensions are a stenholm, one with chromatic locks, an E-lock and one sliding lock, and then a fingered extension (sorry for using the word lock, I forget the right term). Of these, I'm not really sure about the advantages and disadvantages. Either help me and decide which of these is most effective, or help my wallet and convince me to not do anything
Thanks,
Patrick
