Good advice already given, however I would emphasize practicing & working through your particular scenario... Everyone is different in body type, height, chest size, arm length, etc... Of course, we need to bend at the waist to keep the same geometry of our shooting form from ground level to top treestand height AND for varying distances to the target. In addition you still need to get back to full-draw and proper alignment to get the best performance, accuracy, and forgiveness with your arrow set-up (spine)...
I've been in the same boat for several years with a 60" Recurve... My typical treestand height is about 15-17ft to the platform. I was good if the terrain was flat and the deer were 15 yards & further. If they were closer or the terrain had the angle steeper, I would have to do gyrations up in the stand to get the shot off. Not ideal! Every "remedy" I tried from bending to twisting to canting heavily ALL had negative effects and most led to bowstring or bottom limb interference with either chest or legs AND it was hard to get to full draw without interference... I finally searched for a shorter bow and all is well! No gyrations and no mental worries, just focus on my "spot" and let'er rip! I took the opportunity @Kazoo to draw & try 60", 58", 56", & 54" recurves... The 56" was pretty good, but the 54" resolved my issues completely! I now have a Black Widow 54"KB and it's short, smooth, and sweet! I'm 5'10" with fairly short arms 27.5" draw length, larger chest than average. I give all these details just to conclude that everyone is different so play around a little and figure out what YOU need. I received all kinds of great advice that just plain didn't work for me...
