Great, thanks for all your quick answers.  I wanted to get this pack with the Maltby pro series UL shaft rather than the pro series DR- So 47g shaft instead of 60g.  At 45″ playing length.   I like a lighter club and I also am hoping to increase my swing speed, as I am still working on my swing- and that is another reason I want the adjustability of the KE4.  Would that combo work as far as swing weight?
