Matabele,
I'm still testing, but right now, the answer would have to be "yes" from me. I'm looking for "bigger, badder, heavier" in an arrow shaft, as I am not happy with what I've been shooting. I am testing two new shafts - I ordered a dozen AD Trad Lite shafts, and (happily) found that Grizzly Stik offers "test kits", so I ordered two shafts from them to test. Ed at Alaskan Archery Supply is one of the most friendly people I've spoken to over the phone, and he is very proud of what he offers in the Grizzly Stik line. Call him - I'm sure he would be happy to speak with you, answer your questions, and set you up properly. I'm shooting a 47lb recurve bow (Chek-Mate Hunter), and so far, nothing hits the target quite like a Grizzly Stik Sitka - these things are HEAVY, and bad to the bone so far. I've been very impressed, and plan to order a dozen more after these tests are done. The AD shafts are nice too, and I'm torn between the two of them right now. I really like the finish on the AD's (matte grey) compared to the shinier finish on the Grizzly Stiks, but nothing I've ever shot hits quite as hard as a Grizzly Stik.
All the best,
Glenn
