Personally I think the new anti-twist vario system is great for on the fly adjustments. No twisting, no misaligned blade and no wobble.
Just took the new 3 piece on a 2 week paddle in SE Asia and was very happy with both the performance and durability
The new ABS dge blade is a big improvement.
Not saying this is the absolute best paddle on the market as there is a lot of good stuff around now but I think Naish have put themselves ahead of the pack a bit when it comes to adjustable paddles.
