Had a chance to handle a Ten Point (Wicked Ridge) Invader HP last Sat and it grew on me.
180lbs with a attached rope draw that worked pretty slick. Only negative was it did make a little noise from the rope handles flopping around, but I think that could be taken care of with some sort of elastic sleeve I think. This unit had a 3 line scope on it and 3 shots and three turns of the knobs and I was hitting dead on at 20 yards.
Yes, they are a bit noisy but some silencers would help tame it a bit and at 300 plus FPS I think the noise would not be much of an issue...
Price was $549.-- but I found many at $499.-- or less if one looks around a bit.
All in all it seemed like a decent rig for the price if someone is looking at getting a crossbow...Weight was about 6.5 lbs
