I presume you are looking for a used rod, but if not, you can still order new from Loomis, at least you could a couple months ago. I ordered a new one in late Fed 2021. It did take them a little over 3 weeks to make.
if you have a fly shop or other local vendor they may be able to help facilitate. Or you may have to call them if their website doesn't allow a direct purchase. I too got the 11wt and it is an awesome stick. Hoping to christen it on a poon soon if weather allows as the migration is just getting to my part of the coast.
I see you're in Vero, I know as of Monday Whites in Stuart had a 11 and 12 in stock. Both NRX and Crosscurrent I believe. If I didn't just find a 10 I wouldve got the 11 for a back up, now have a 10-12 crosscurrent and love them.
