I shoot an Aeroforce and have an old H500 as a backup, and the company still keeps parts in stock for them all. Speaking of parts, any tiro with a modicum of handyman can work on these bows, right down to stripping them to the riser, if you want. And the reps at the factory, will talk you through it-- personal experience: I had a lower power cable blow out on the Aeroforce (dunno how many arrows through it, but I've had it for a decade, at least). The company had a new set of power cables to me in two days. The timing cable was pulled out of adjustment, and Matt talked me through the readjustment. I lined up and tensioned the timing cable, installed the two new power cables, retillered and cranked up the limbs, and was back on my elk hunt last week with just one day down. The bow is bulletproof-- nothing else was tweaked, twisted or damaged. Heavy? Maybe in terms of a few ounces; certainly not pounds of difference. I bought my first (the original H250) because I was a string shooter, and they were long enough to be forgiving. Loud? Not particularly, if you work on tillering, timing, and string silencers. They're fine bows, and hold their own speed-wise with the wheel bows. Nothing to be ashamed of in using one.
