Would you like an independent review of a rod range? Here's one from Roger Hoad on the Vision Onki

I now have three Vision Onki 9'0" rods in what are probably the most popular line weights.
First impressions of all three rods are of a nice slim blank, lightweight (78,79 & 82 grams respectively) and a high quality of finish especially for rods in this price range.
The #6 weight was unusual in that it had the short Full Wells handle which I didn't think that I would like in a rod of this length, however it was so comfortable in use that I completely forgot about it.
The 'waggle' test indicates that all three of these rods are stiffer than the 10'0" #6 that I reviewed recently.
The back garden casting test showed them to be very responsive and accurate at all distances, in fact when trying the #5 I aimed at a garden cane sticking up from one of the flower beds and landed the line across the top of it.
Of course it's all very well casting a rod on grass but the real proof of the matter is how does it fish? The answer to that is very well. Over the past three or four weeks I have been fortunate in catching some really good conditioned overwintered rainbows up to 4 1/2 pounds that really put the two heavier rods through their paces. The cream of the crop was a brownie estimated at 8-9 lb on the #5. That fish fought really hard and my arms were aching when I eventually netted it but the rod handled it well.
I know that the manufacturers class these rods as medium action but I would class these three as fairly fast with an extremely good recovery, plenty of power and accuracy but all contained in a user-friendly package, certainly not the pokers that we used to see branded as fast action. All of these rods are very accurate at all distances but of the three the #4 and#5 excel at short to medium range losing just a bit of accuracy at distance.
All of these rods perform really well when playing fish with plenty of give in the top half of the rod to protect hook holds but a good stiff butt to control feisty fish. Both the #5  are very capable when fishing weighted lures but also have the finesse to fish dries and nymphs well. The #4 is a lovely dry fly and nymph rod and a delight to use.
I have also tested all three rods by underlining and overlining them. The results were quite different from when I did the same test on the 10'0" rod, mainly I believe due to the stiffer action of the 9'0" rods.
First up was the #4 weight. The rod performed well with a #3 line, the word delicate came to mind, although it put out a good line it didn't shoot very well. With a #5 line it cast well and the line shoot was phenomenal with no sign of the line overpowering the rod. Accuracy was good with both lines.
Next up was the #5 weight. The rod performed well with both line weights and pick up and line shoot were extremely good with both as was accuracy.
Last was the #6 weight. I didn't feel that the rod loaded particularly well with the #5 line although performance wasn't bad. However with the #7 line it was an altogether different beast, it lifted a really good length of line and shot it out with no problem at all. With very little room to backcast it put out nearly a full line with only two false casts.
I used WF RIO Gold lines on all of the rods and an Orvis #3 and Hardy #7 when under and overlining the rods.
Once again a very impressive set of results from a superb range of rods.
