I was there in May rode my Yeti 575 hard for 3 days it was more than enough bike for everything.
Good points
All the courses are very progressive yes they have big stuff and some stupid stuff but you have the little stuff next to it to work on your technique and you build up to the bigger stuff.
during the week its quiet (no queues)
4 courses all are quite short you end up sessioning them alot
Giro (berms and little table tops)
4X waste of time
Continental bit of board walk and quite progressive into fun park
DH track you can ride this on anything watched a crazy german ride it on an XC hardtail with the saddle up round his ears he survived.
Bad points
Its small and at weekends gets very busy
in the wet the board walk is very slippy
I didn’t go and ride any of the XC as was there to ride the uplift stuff, the one German I spoke to about said you need a guide for the “good stuff”
Good luck the town is nice make sure you go to the Irish bar they like a drink and the steaks are epic.
