Ya ... unless yer 8yr-old ... 'er 'bout as weak ... I'd get a 60 lbs bow! (
most'll be adjustable down to 50 lbs) ... 'sept a Mission Venture ... then I'd get a 70 lbs bow ... that one's adjustable down to 50 lbs! I bought a 60 lbs, but I intended to always shoot it max'd out! My other bow is 70 lbs ... adjustable to 60 lbs ... and I've got it around 65 lbs! ... but I wouldn't wanna go much lower ... to do so, ya basically loosen the limb-bolts! ... and I'd rather not loosen to the absolute minimum!
The Venture's also got an ATA of 'bout 30in ... that's as short as I'd go ... it's not an issue fer me, physically flingin' an arrow ... but I'm not a dwarf ... and by the time I got my peep where I wanted it, and then set the sight, so it'd hit within' an inch, it barely clears the riser!

My Quest is a 33in ... I think that's the cat's ass! 35's appear to be more like target bows ... at least, there's a lot less of 'em, designed fer hunting! IOW, as the ATA goes up, yer choices go down!
I'd focus more on brace-height ... 'sposedly it's the distance from the riser, to the string (
at rest) ... and 'sposedly it has to do with the bow twisting, as ya shoot ... I tried 'nuff bows, that while I don't know the specifics of it, I'd definitely stick with a brace-height of at least 7in ... 7.25in, bein' in the "
comfort zone". It appears, fer the most part, as brace-height increases, speed decreases ... I ain't sayin' that's a given ... 'er linear ... jest, most of the bows with a brace-height over 7.25in, seem to generally be closer to 320fps 'er less ... whereas, the shorter ones get over 330fps ... fer my money, I'll take the longer brace-height, every time!
Fer hunting, ya might also wanna consider the weight ... again, this is where the ATA's gonna work against ya ... the longer the bow, the heavier it's gonna be!
Not to beat a dead horse ... but ya consider price, weight, brace-height, speed, warranty, reputation ... and then, when ya actually shoot one!

... that Venture's an awful lotta bow fer the money!
Also, while most shops'll have a "
guest" release ... that's to use to try out one of their bows! ... don't know how they'd feel 'bout lettin' ya use it to try someone else's?!
If ya don't already have a release, ya might wanna look into that, first! ... here's a strap-on, I like!

...
http://www.dickssportinggoods.com/product/index.jsp?productId=3982132 ... it's a lot less expensive than a lotta other releases! ... it was the first one I bought (
jest dumb luck) ... and after a few months, I had no issues with it, but I thought it'd be cool to get a "
really nice" release (
read: expensive) ... I tried a dozen 'er more ... I ended up buyin' another one of these Scott's ... after tryin' most everythin' else, and ALL of 'em sucking ... I then realized, if mine ever broke 'er was lost, I'd never let myself live it down, that I didn't buy a back-up!
Fer a sight, I went thru a few 5-7 pins ... then I tried this one ...
http://www.dickssportinggoods.com/product/index.jsp?productId=4314675 ... it comes with stupid easy instructions on how to figure out which "
tape" matches yer bow/arrow's trajectory ... ya stick it on, then set it to the yardage yer shootin' ... mine's within about an inch up to 50yd (
not that I can hold an inch at 50yd, but my group's centered well 'nuff, I can't adjust it in any particular direction). I shot 3D with it ... biggest thing was guessing the yardage (
if ya don't have a rangefinder) ... but if yer guess is close, it's almost like shootin' a carbine! Ya can accomplish more 'er less the same thing, with the 5 - 7 pins ... but jest in my back yard, I've forgotten which was which, 'nuff times ... I've lost a few arrows!
Fer a rest ... and I'm certainly no expert ... I started with a whisker biscuit ... still have it, on my Quest ... my Mission, I had a limb-driver put on, right away ... the limb-driver's neat! ... no two ways 'bout it! ... but I'm utterly unconvinced, it performs the least bit better, than a biscuit!

Only thing I don't get is, why's the replacement biscuits so expensive?!

... that said, I'm still on the original on my Quest ... it's seen a lotta arrows ... but now it splits time with the Mission ... so I dunno ... I think they hold up purdy well!
Most any idiot can put on a d-loop, and a peep ... but I'd go to a pro shop, and get fitted fer 'em! I started with a G5 peep ... it was very large ... I even got comments from league shooters on how overly large it was! I switched to a deallie where ya can screw in a smaller aperture ... and I put in one of the smallest ... it helped ... but then when I shot closer to dusk, it was almost impossible to line up a shot! I'd probly go at least 3/16th on the aperture ... and I wouldn't go with the screw-in deal, again! ... it came loose once whilst I was shootin' ... and took me a few minutes to figure out where the new sound was comin' from!
