chrisfx811, sorry, just found your question.
Pretty good answer from sonoma9600.
The Dynalite Gold wood shafts will definitely launch the ball higher with their very soft tip flex. They also feel quite solid even when you slightly mis-hit it. I recommend them for a smooth swinger because there could be directional control problems with a slasher (my temporary, thought of the moment, new word for a very aggressive swinger).
Also, as you mentioned, the cost of some shafts are quite high (my take is getting more like ridiculous) and most of them certainly do not give you the performance benefits equal to the higher cost. The True Temper Dynalite is a very good and consistent shaft in the 7 to 8 dollar range. It has also been around a long time for a reason; it works.
