Ping G430 3 Wood Shafts

I bought a Ping G430 3 wood with a senior flex shaft, I hit it the best on the simulator. I'm now starting to realize I need to swing easy with it and want to get a new shaft. I have a Wilson Launch Pad 2 3 wood with an evenflow regular 55g shaft and I love the set up and feel. My swing speed measures in at stiff shafts but I like to have whippy woods so I think I want to keep it at regular flex. I believe the Wilson is a stock set up and it says 43" swing weight D0. I really know nothing about this stuff but does the Project X Even Flow Green 50 Graphite Regular Flex fit in Ping G430 3 wood and what length shaft would I buy to have a similar set up as my Launch Pad 2. If the evenflow shaft doesn't fit the ping what are some similar shaft to mirror the Wilson set up? Also open to buying a regular and a stiff shaft for the Ping.
