Although I like the Gti's as a drift rod, I don't like them trolling for larger game because of the level wind. If you want to catch tuna and wahoo you need open tackle due their speed and power. Just my opinion. If you can't afford all that graphite I do recommend Penn Senator 4/0's and 6/0's. The red sided ones are very capable and affordable. We did, however, find most of our Penn Graphites and one of our Shimano 50W's at pawn shops. We've also found some amazing lures for $5 each. You just have to look pretty hard.
