Re: tfo rods..what's the difference?
If you are going to be spending 30 to 60 days on flats, you may enjoy the new BVK over the TiCr and TiCrX models. I have casted the 5, 6, 8, and 9 weight models. The BVK is over an ounce lighter, so your casting arm won't feel as fatigued by the end of the day. The rods can handle the heavy payloads (larger flies, heavier lines) that the other rods can, but the caster does not have to work quite as hard. The butt end feels plenty stiff to handle heavy loads from fish and well executed double hauls. I think that the BVKs rival some premium rods in performance.
The only thing that I dislike about the BVK series is that the 6 weight does not come with a saltwater reel seat and fighting butt, but that is just a personal preference.
Edit: BVK prices are $224.95 for rods sizes 3 to 6 weight and $249.95 for rod sizes 7 to 10 weight.
