I got the Middy pole a couple of years ago. I was in a similar position to you as I had very little pole experience. Started fishing the canals and small ponds for anything. I ended up changing the elastic as it came with quite heavy elastics fitted. It is a great pole, easy to handle, robust but i was disappointed that i could only reach halfway across the canal. Have toyed with gettin a longer pole but for the amount I use it it would not be worth it. I get the impression its for absolute monsters very close in. If your fishing for anything then you may want have the option to go further out but with lighter setup. You can make a pole shorter by taking sections off but you can't make it any longer. Middy do a longer version called the Thriller I think. It might be 8m. Can't remember. But I would definately get another middy pole. 6m may be perfect for your type of fishing though.
