I'd go for the Top Case ( Trunk ) too - you will find it really useful on the occasions when you need it

Your stock seat may "break in" a bit after riding for a while,
such that you don't need a Touring / Comfort Seat, but even if you find that you do need one,
they come up for sale now and then on eBay etc, and in the "items For Sale" section of this Forum,
whereas Top Cases don't seem to be offered for sale to second owners very often at all.
Cheers
