Yeah I've had a nosey at the cyprinus bunker it looks pretty good to be honest I'm just not quite happy with the height I watched the carpology review on it if it was 20cm higher I would snap it up. The main 2 I'm torn between are the jrc extreme tx and cyprinus K2 mainly because of the inner vapour guard, I'm trying my best to find anyone who's owned a K2 to give me an insight on the quality.
