Ok, DC. I'll bite.
Let's look at your numbers, shall we. For instance, you will be hitting that 42 lbs of draw right around my draw length. Easy peasy draw, I can shoot that baby for long sessions without any ache in the elbows or shoulders. No real chance of developing bad habits or the like, either. A mere forty-two lbs of draw? I'm not out there to slap it on the table in front of the guys to measure against what they got, what would I care?
Then if you were throwing ten grains per pound of draw weight arrows, you could expect the old '100 plus the draw weight' to be a benchmark for an efficient bow, so 142 fps? And you got high 150's with a 439 grain arrow. Fine. Completely within acceptable territory.
I have never really had an effective range beyond 20 yards and would prefer to shorten that whenever possible. If all I could get outa that bow is 142 fps, that 20 yard shot would have an arrow flight time of 0.42 seconds. These ain't wheelie bows chasing the 300 fps demon. Plenty quick for anything I would need.
Yeah, it's not in the top tenth percentile for performers, but it is deep into the "workable, every day shooter, meat maker, pretty on the wall" sort of bow. No shame in this darling.
