I agree. There isn't much out there. I keep trying the newest arrow and kite shafts, but for hoops and arcs, haven't found anything currently available much better than Fibraplex. That is why I turned to tent designs with much larger radius bends, using stiffer poles and alloy elbows. Thanks, Roger.
The Easton FX carbon tent poles are much beefier and quite a bit stronger, and in my break tests were about 25% stronger, almost as strong as the Easton .344 alloy used in the Moment.
The FX is just under 12 gpi, and the .344 is around 13.7 gpi, only a 12-13% drop in weight with the FX, but it is something, especially when you consider that the FL alloy poles that come on many of the tents are over 16 gpi. Haven't tried to break one of them, though.
Roger is strong on the Victory Archery, available in Canada, which he thinks are very similar to the ones he buys locally in Australia, but they didn't test much better than the Fibraplex in my break tests.
One caveat: A break test doesn't show how well the poles will stand up to repeated flexing over time, nor does it show crush resistance. But I had to start somewhere.
One problem: As noted by Travis, Easton only sells wholesale. They were willing to sell me 100 of the FX sections with their alloy ferrules, no less. I decided to wait on them, and keep looking.
Another problem, oft-noted by Roger: The carbon shafts are made in Asia, and i have found that the quality, strengthwise, is not consistent. That is why, IMO, some do OK with Fibraplex and others experience early breakage.
Will keep trying carbon shafts because I love dome tents. It is frustrating, because every new shaft is grandly touted as stronger, and so far, is not. But am currently looking at several possibilities. Expense means delay, because I do not have a lot of $ to throw at the problem. If I find anything good, will post it pronto on MYOG.
