Quesstions about Aldilia NV shafts

Last year I went to Club Champion and was fitted for a Aldila NV KXV Orange 75 s shaft for my Epic 3W. And I was fitted for a Oban Devotion 6 03 shaft for my Epic driver. I now have the means to get both of these shafts. But, Golfworks doesn't have the Orange 75 in stock. They have the 65 in stock. My question is: How much different is the 65 from the 75 in terms of performance? The price and time line for the 65 is much better than Golfworks ordering the 75 and doing the work. Also, they have an Aldila NV 2KXV Orange graphite hybrid shaft at a GREAT price. I'm thinking of getting one for my Epic 2h which I can NOT hit with any height or distance. What are your thoughts on my shaft thinking for my driver, 3W and my 2h?
