I've recently purchased an Aeron Hybrid boom, i.e. V grip and carbon tail. This is the second Aeron I've used, the first being the older alloy only version which i borrowed. I replace my booms at approx 18 month intervals; I think they take a hiding and really don't like it when they fatigue and fail when out the back.
I reviewed the earlier Aeron boom, the new one is great. I'm using it as a direct replacement for my X6 (which was great as well, except for the weak as boom clamp) and i use it on my sails from 5.5 thru to 7.5. I'll have to double check the boom size but, without going to the shed (and its raining outside), i think its 170 -220.
FWIW, the main points I like with the Aeron Hybrid: clear absolute boom markings, FANTASTIC articulated boom head, snazzy boom tail complete with all pulleys for adjustable outhaul and lastly, price point.
I love the boom head, as I did with the borrowed one, because of its very well built nature and intrinsic strength, i.e.triple hinge point. It looks the same as one of the picks above.
As for the main selling point, the V Grip, well, I'm used to it now, but it did create a new line of callouses. However it now feels very comfortable. With respect to stiffness and strength, I'm not qualified to say, in comparison to other current booms, except to say it feels good. As for the tail, the carbon finish looks very trendy but the captive pulleys are the go when rigging an adjustable outhaul. The Sailworks NX 6.2 and 7.2 I have are made to use with adjustable outhaul, so it integrates well. I'm one of those folk that can't bring myself to spend on a full carbon boom again (having the belief and experience that they break just the same as any other boom).
Overall? Very happy with this boom. In conjunction with my new NX I cracked a new Alpha PB on the second outing.....
