As noted in my thread that I have a kurenai 30, but have only fished it a couple times.
I would not sell the rod, but I am not sure if I would recommend that particular config either…until I figure the rod out a bit. I may need a season or two to do that.
Unlike any other rod I have purchased, this rod requires some dialing in. As I noted the casting is perfect, the challenge is the strike detection. I feel the tip might be too soft for my fishing style where I rely both on feel and sight. I do not regret my purchase. It is a rod that requires a little more work to figure out. It probably will make me a better angler.
The lightness in hand of the kurenai is just crazy. It make my tenkarabum 36 feel like a telephone pole.
I know nothing of the X35.
In terms of rod length, I would choose based on length you are most comfortable and the canopy you intend to fish this rod…over the size of fish. Rod length and size of fish do not have to correlate. I chose the 30 for the canopy I intended on fishing. I am sure the 33 and even 39 probably have similiar attributes. Read the customer column on the kurenai page at tenkarabum. Lots of positive reviews and interesting data.
There has been a lot of hype about ultra light lines. I am not a skilled caster but was easily able to cast a 2.5 Level line and would bet I could probably cast a 2 Level Line without a problem. Small light flies match up nicely. Beadheads, bigger, or weighed flies do not cast very well at all…they overload the rod.
I see my kurenai 30 to shine in shallow water presentations. Like brooks 3-12" deep.
