I just bought a Drennan Carp Pellet Waggler rod which you can fish at 11'6" or 13'. It's very good and handy that you can fish it at 2 lengths. It's only handled carp to 3lb so far but seems to have a lot of stick through the middle and butt as well as being able to chuck heavy wagglers and it's only 90. I think some lads like the Carbonite rods but they are more expensive.
I use a Browning 8010 reel so you can 'finger' the barrel instead of using the drag but they stopped making them years ago (shame). If you like using drag then some of the Shimano reels have got a clever system where you can use a small lever to increase or decrease the drag easily when playing a fish, it's instant and better than messing around with the main drag knob. Other than that the top-of-the-range Daiwa's look very tasty!
Not sure about the Avenger and what it can handle, sorry.
nick the 11ft carbo mini i used i found it was poorly constructed and not nice to use really, so i settled for buying a few maver genesis 12ft rods.
They had a nice finish and almost a better through action than the carbos only difference the minis are stiffer thn the genesis.
small reels like your TD-sol are perfect for the method. i agree heavly with a front drag reel and loose clutch so you can hit the fish and let them run if they bolt off.
I use a Preston 11ft mini rod for all my pellet wag fishing it casts brilliant and has a brilliant fish playing action. As for the reel I would either use a Daiwa Tdr or a Shimano stradic with a front drag both these reels are brilliant and just right for this type of stuff.
