Please don't laugh ... but, of course you will !!
I was back in a Lidl store today & there were a couple of fly-rod kits loitering and, yes, you've guessed it, I did indeed buy one (£30). It's a 240cm (~8') #5/6 rod with all necessary lines & a few flies.
My compete novice assessment would be that it is no faster than "moderate" and maybe even a bit slower than that !??
If I had known that its in-bag presentation as a r-hand reel was wrong I might not have considered buying the kit at all and, alas, it is actually a l-hand reel !
For saltwater fly'ing it is almost certainly a bit light with limited overall line-capacity also, but, if I can get on with it at all, I will try out with FW7 line idc.
For £30 though, I reckoned it will let me know whether 'proper' salt-water fly-fishing gear is something I might want to invest in. I will practice fly'ing techniques on my fields (i.e. on dry land) so the only initial challenge will to make a dummy-fly fly over the daisies (or not) with no public humiliation what-so-ever.
Not much lost if I can sell just the rod to another fly'ing try-it-out beginner, say for, a fiver !
