Hey Christian !!!!
Great to see you on here again.
Feared that we'd lost you to puberty and rampaging hormones. Glad to see you seem to have survived !
I'm not that far away from you and I have a stable of recently not very much used fly rods running from 7 ft wands up to 10 foot reservoir smackers and associated reels and stuff. All of which you are welcome to have a wee waggle with and possibly borrow to try out fly fishing if that would help... ? If you're not sure whether fly fishing is for you then trying it with borrowed tackle is a good idea, as if it doesn't work out then you've lost little.
Then again, getting used to the consistent feel of your own rod when learning to cast can't be beat.
Mark's link is a goodie, not to be sneezed at and basically everything you need. If you can afford either kit that's a damn good starting point.
If the budget won't quite stretch that far have a look at Bennetts of Sheffield's starter kits
Fly Fishing Tackle - Outfits, Rod & Reel Combo's and Tackle Packs
It's certainly where I started my flyfishing career nearly 40 years ago on 2/6d a week pocket money ! Two shillings a week on tick for months on end, and then my first magical Shakespeare glass fibre fly rod and reel arrived ! Great days...
Looking at the Deluxe kit (
"Deluxe" for £69.99

) I'm not sure whether I'd go with a 9' 6" #7/8 rod as a first rod unless you are completely sure that you going to be dedicatedly fishing fairly large lakes and fishing at a distance. It's a lot easier to learn to cast reasonably and reliably on a shorter rod than that. Myself, I have always preferred small waters, rivers and streams and an 8 1/2 ft rod as a river all rounder, stepping up to a 9ft on larger rivers.
The Travel fly outfit is also worth thinking about. Although it is still a 9ft 6" rod it is a slightly lower 6/7 line weight and while you may well soon outgrow its limitations as a starter rod, it is always very useful to have a suitcase-friendly travel rod at the back of the cupboard to pack for holidays away...
(Once upon a time 20+ odd years ago I wouldn't have dreamed of suggesting anything but a two piece rod for sweetness of action without flat spots, but the improvement in design techniques and quality since then means that multi piece rods are often nigh on indistinguishable in action to two piece rods).
Anyway, think about it and do your research, and pick the brains of those on here with many more bank-years of experience flyfishing than I will ever have, then go chuck your fluff with the best of 'em !. And if you would like to meet up and borrow a rod from me then pm me and we'll set it up.
Cheers ! Really nice to see you back and posting too
PS. you don't seem to have PM's open... ?
