I am seling a T&T 12 wt and a Gulfstream outfit. I bought it for my Xmas trip and won't use it again I bet. If he is interested I still have it for sale.
The RPLXi is a good rod to. for a 12wt you want something a little softer so the casting is easier. 10 is too small for tarpon. It would take too long to fight them and it would eventually will spit the hook. A 9 is a good size for Florida bone which run big. If he wants to get into SW don't even both for florida Bones or permit unless he is already a really good flyfisherman. It is so hard. I would focus on tarpon and snook and albies.
