I do have a reasonable class legal #2, and use it probably more than BeBop does. I would not mind changing the material to allow kevlar so it can retain its shape better over time.
If I happened to drop my spinnaker pole into Loch Mich sometime, I wouldn't mind replacing it with carbon... mostly so my 118# son can handle it easier. This is a change I do support.
As to adjustable genoa cars, it seems to be an expensive change (if done correctly) with no real benefit.
PLEASE phase any sail changes in over time. Bob's chronology seems reasonable to me.
On lifelines... I've been on a Mumm 36 whose lifelines had rope lashings. The lashing failed and dumped one crew into the water in rather nasty conditions. I would hope we can continue with the current setup.
