what head weight should i use on a FD

I just got a 910F 13.5 with a Speeder VC 8.2 tour spec X-stiff shaft. i was wanting to try a 13.5 FD head on that shaft and see how i do. what weight should be in the FD head.

thanks cheers greens and fairways 



They will both swing weight out the same, so the weight you currently have won't change the swing weight.



Thanks Cameron

Thanks I made the head swap. I am definitely hitting a more boring ball flight with the FD head. and during my round with it i found the 13.5 to be too long on some holes. Good news is i recently bought a 19 degree f model and i hit it 250 so it is working out great.

cheers, greens and fairways
