The original DTX or maybe a G2 Mackenzie (you might pick one of those up for the mid-£300 bracket second-hand) would be my choice without question, lots of other nice rods out there but I can't see past Mackenzie rods, for me they feel just right.
The question of reels brings out something of the tackle tart in me, nowt wrong with the one you've mentioned but a reel is more than just a line holder and from Vision I'd buy a Tank..... ask Euan... he did. Twice.
Lines - to be honest the Barrio ISS is my 'go to' line these days but I also have a multitude of full lines, shooting heads and Skagits from Rio, SA, Mackenzie and Airflo plus many others. Each have their place in my armoury, so I guess the question is which line is likely to be the easiest to use where you're going to be fishing
Chances are the shooting heads will be as would the ISS.
Happy to discuss this for hours.....
