Best guide by my estimation is Jason Wilhelm. Stuffer and Manboobs went out with Jase and he was great. Good bloke also which helps. Think he's still up there but not entirely sure.
Best month? Hard to say. Probably want to give it a few months from here to let it settle a bit but I may be wrong there. I've had most luck n Feb. I think it's been quiet for a while but others will know more. Pretty sure the Boyne below the dam is still holding the odd one, so you may get someone to take you into that country?
Good luck. Getting that first hit by a big barra will absolutely blow your mind. Addictive!
