I'm building up my skills on a 'comfort' hybrid with a view to doing light touring later in the year - rides of several days around the region where I live, carrying overnight gear rather than camping gear.
It's a bit hard to determine from the photos I've been able to find, but if that Giant hybrid has comfort grips I'd suggest you wait a bit before adding extenders, to see if you really need them. I added extenders to my hybrid, but found I rarely use them at all, because the comfort grips allow me to relieve hand discomfort with very subtle adjustments to hand position.
