Aye - Cracking pictures there!
There are a lot of pike at sweethope, however nearly all the pike I have seen have been in the small loch. My farther had 7 one day (whilst fishing for trout) where the outlet is near the weed bed, all to the Fly, (gold head damsel), all where small jacks a couple of pound, however I have seen some much bigger fish lying in the shallows.
