Hi
My wife and i were over there in March this year,NOT a fishing holiday but i did take gear over with me.The guys on here gave me plenty of advice as well.
Just remember that you will need to declare on the customs form that you have tackle with you and it might well be inspected to see if all items are dry.I had no problem, but then my luggage went awol for 24 hours and i had to leave keys with customs but am pretty sure it never got opened-never got the keys back either

Don't take tying materials either.
Although i did fish alone,and caught,i did enlist the b and b proprietors guiding on two occasions (half day trips)which was really very useful and got taken to some really nice stretches of river.
I found tackle pretty expensive over there,i did buy one or two small items as its hard going into a tackle shop and NOT buying anything

Wonderful place,sure you will enjoy it.
