well Christian, i'm not quite sure what you mean on your first paragragh, but on the second paragragh, i can't aree with you on that, if the shaft is too stiff for your swing, you have no control and you'll have loss of distance, now your forcing the shaft to work for you. a shaft thats too soft, with a normal swing , may have loss of contol, but you can to adjust your swing to the shaft, that's definitely not preferable, but can be done fairly easily.
you are absolutely right on your third paragragh.

i don't think he quite understands that the LDC is a whole different ball game (like the MBL to high school baseball) even though the same principles apply.
