Looking at the Prism Tensor or Ozone Octane to prepare my kite handling skills before trying kite surfing next summer.

Would either be a good recommendation and should I go 3 or 4 meter to accomplish this better? I am thinking bar on both even though Tensor comes with both handles and bar which I like.
Btw I weigh 180 and my winds are usually 7-12mph where I live, inland.

either would be fine. You might want to check out the hydra by HQ.

What size would you recommend, 3 or 4 m? Given that I want to train for kite surfing would a kite with more pull be better or would the 3 m be better that wouldn't pull quite as hard?

Depends on our normal winds. We usually get 12 mph and I would probably go for a 4m if I was going to work on kite control and body dragging.

Hey NPH!

Well, I can only speak as to the Tensor, as I just recently got a 5.0 and I must say that I love mine. It is nice that Prism offers the switchable bar/handle combo, as you can experience both feels without having to purchase anything additional.

As I can say, I can only speak on the Tensor, but I was impressed with the construction and the quality of the accessories, including the bag, which is very nice indeed. The kite killers are very well constructed and all the sewn points look and feel durable and well stitched.

I chose the 5.0 due to the typical winds I have in my area (less than 8, generally), and in 5-7, this guy can pull quite well. If you're in a windy area of 10+ and looking for a trainer, I would suggest the 4m probably, as the 5 would give you possibly too much pull.

Best of luck on whichever you choose!

Finally made up my mind. Found a great deal online which included an instructional DVD and Tensor 3.1. It is windy season in Dallas and it should be here before the weekend.
