% Actually the more address space allocated, the harder it is to be found in
% that address range.

% Not at all, but if it takes an attacker 500 billion years to scan a /64
% at one IP per second, I' happier than it taking 4 minutes for an IPv4 /24.

	from this side of the fence, since there are so many discrete
	IPs in a /64 that you are being announced, that looks like
	a target rich environment for forged source addresses for spam. 
	but, as you point out, YMMV.
