slow swing speed needs a 5 wood

That seems like a great choice of clubs to me. I would be happy if your 5 and 7 woods were relabelled as a 4 and a 5 wood as their lofts accord with what is imprinted on my (probably outdated) brain. Must be over 12 years ago that I bought Ping G10 Driver, 3 wood and 21dg hybrid. Great clubs, but the slowing of swing speed with the advancing years made me feel they were no longer suitable. Before I make a radical adjustment, I've been experimenting with some even older clubs. At present I am using a Cobra Fspeed driver and matching 16dg baffler hybrid. These have a much heavier "feel" to me than the Pings, but with the slower swing I get the feeling of a very solid hit, whereas it started to feel like an ineffectual waft with the Ping driver and 3 wood. Still using the Ping 21dg hybrid though.
The marketing of new drivers and woods does not seem to be directed at the fairly good but aging golfer (apart from shaft choice) so it will take me sometime to consider a new choice of the three big bats. Because I'm getting on so well with the old Cobras, I am keeping a watchful eye on this brand. Like I said, your choice of 1,4,5 (to me) looks a good un.
