Not necessarily a youth bow, as you call it. Just look at bows designed for shorter draw lengths---people of shorter stature. Several companies make such bows. I know Bow Tech has one, but I can't remember the name.
I'm almost in the same boat as you. I shoot just about 26.5" and many of the bows that interest me start at 27" and go up. Well, I know that won't work. A good example is the 2010 Martin ShadowCat; just the bow I've been looking for for several years, but it won't go short enough. So I had to settle for a second choice---Rytera Alien Z with Hybrix 1.5 cams.I'm right in the middle of it's draw length range so I have room to play either way and still get decent performance.
Right now I'm shooting a Martin FireCat that supposedly goes down to 26", but I've actually measured the AMO draw length on the shortest setting and it's 26 5/8". Not really complaining because it fits me to a "T". Just that pound for pound and inch for inch the efficiency would be higher and get higher speed if I were shooting near the top of the draw length range. How much might be open for debate, but us short guys need all the help we can get.
And I might add that I'm concerned about speed for 3D. Normal hunting ranges for eastern hardwoods whitetails doesn't concern me one bit. I been doing this for over 3 1/2 decades and shot deer with bows shooting as low as 190 fps and blew right through. My average speed in a hunting setup usually ends up about 265 fps so I don't fret about speed or kinetic energy. Guys make too much of both of these issues.
