Try everything---if it doesn' t " float your boat" , then you can say it' s junk with finality,(I' ve done this with many new " fad" items myself) but alot of times we all might find something just a touch better than what we used to have.
I haven' t fought it. I' ve wasted a lot of money over the past few years trying the new bows, new arrows and such (nearly enough to buy a new truck!), and that' s why I can safely say, with finality, that it IS junk, at least for me. This stuff demands too much perfection. Your form has to be perfect. Your arrows have to be perfect. Your tune has to be perfect. Your concentration has to be perfect. If any little thing is NOT perfect, you' re screwed.
500 fps might not be a pipe dream, but it' s going to raise the need for perfection to a whole new level. I don' t think a human being would be able to control it and we sure don' t have any carbon arrows that would be up to the challenge. Factor in the tolerance slop with inserts, nocks, heads... It would take a quantum leap for the manufacturers to produce components for arrows that would shoot out of a bow like that. When the time comes and they' ve shrunk their tolerances down to practically nothing, who will be able to afford to buy the stuff, other than Bill Gates?
A whole lot more guys than there are now will be whittling their bows out of tree limbs again.
Like the old saying goes, be careful what you wish for because you just might get it.
