Doug,
It sure does look a cracking hole.
When playing shots near UK railway lines I understand the best method is to check the train timetable before you play your shot. This is because UK trains have been known to run late so if you play your shot when the train is due to pass it's probably not going to be there!
Jeff,
The 8th at Narin & Portnoo is a great choice, definitely a fun hole, might be more than 325 yds though, but what the hell. The 1st at N&P is a pretty good starting hole and I think that's under 325 yds.
The hole with the high tee at Cruit Island is the 7th. Cool hole. Indeed, numerous cool holes at Cruit.
The 13th on the OTM course at Rosapenna might be pretty good choice too, must be 325 yds or thereabouts.
