I used a koho stick back in the late 1980's that I think was fiberglass. It may have been called the K1 or K3, but that was a long time ago. It had an oval shaft. The fiberglass was wrapped with about a 1/8" overlap all the way up, so it looked like it was ribbed. I think I used it for about 6 years; the shaft ended up getting cracked on a hard spill into the net.
I was never clocked with that stick, but I was consistently at 90mph +/- 3 using a Montreal 44 wood stick. I always felt the shot was quicker with the Koho, but it always wanted to go high, and it took more effort to keep the shots low. Playing D, the Montreal 44 was great for breaking up passes, the puck would just stop. The Koho was so light, plus the shape of the shaft, that the puck would most times bounce off the stick and out of reach.
I have not tried a fiber/composite stick over $150 today, but I would take that Koho over anything else that I have tried.
