It's not what they are designed for, but has anyone ever used a Micro Fly Rod/Reel at a UK Trout Fishery?

I have fallen in love with the Micro Rods/Reels at www.jaustinforbes/micro, but I am unsure if they will be fit for purpose on a commercial Trout Fishery. My local fishery is small enough to not worry about distance casting, however I don't know if they'll take the weight of a large stock trout at fisheries such as this. Does anyone have any thoughts/advice?
