£700.00 seriously? Never give that shop your custom again!!!!
What fishing are you planning to do river stalking, or boat styling/bank fishing small stillwaters?
I'll help out with Rods and hopefully other members will advise about reels/leaders/flies/accessories...
RODS
Bank fishing and boat styling can be covered effectively with a 6 or 7wt 10ft rod as a starter. I'd go for a 7wt myself. Many/most never buy another rod for these purposes although some eventually opt for really long rod for boat styling of 11ft and a 9ft 6" casting tool for bankfishing.
Rivers a 9ft 4 or 5wt rod will cover a lot of bases although you may eventually want a 10ft 4wt for Czech nymphing later and maybe a 7ft stream rod for little trout.
(I get by fine with a 10ft 7wt and a 9ft 5wt and a 9ft 9wt for pike and salt and don't plan on buying any more rods for a good while).
Any rod from £80-120 is likely to be a great tool, will probably have a lifetime guarantee, and will last you years cared for properly. Greys, Snowbee, Sharpes, Guideline all do excellent rods in this price range. Some entry level rods are brilliant tools - the Shakespeare Trion is raved about at it's price point of £30ish - no guarantee though. Unfortunately some entry level rods are complete mince.
I know you are after a river rod but if you fancy ever doing some boat and bank fishing stillwaters (most do since rivers are harder to fish and cast) - I like the Snowbee Diamond at this price point and if there are any 10ft 3 piece 6/7wt rods still available in their warehouse clearance
Warehouse Clearance Sale at £64 I'd snap one up. That's a load of rod for the money wish there'd been that deal when I bought mine.
So your boat/bank starter is 1 x rod at £64.00... let's see if we can recommend a 2 great outfits for less than £200.
That's all for now.
