I'm 6'3" as well. 75" tip-to-tip wingspan. I use a 30-1/2" BOP shaft and my favorite bows are my Browning Explorer (62"), my DH/Martin Dream Cacher (60") and my Browning Cobra (58").
As to stacking: I have never had a problem with any "modern" Bear recurve, and in fact my Kodiak Hunter starts to perform much better once it gets past 28" draw. The man I bought it from was at a indoor shoting league with me and when I started to shoot it a week later he came over to see why my arrows were so much faster. Mine were, in fact, longer and heavier than his. I was drawing 3" more and it made a big difference in how the tips unwound. When I shot target recurves I drew 31". My first hunting recurve was a Bear Kodiak (60") and I drew that 31" with no problems. Still have it.
That would be an excellent bow to start with: a Bear Kodiak Hunter. They can sill be found for $100.
While I like Damon Howatt/Martin I have had a history of banging my head on them. I was offerred a Mamba (58") at a good price that I wanted badly but it had the stifffest stack I have ever come up against. Even the 62" Hunters (Excellent bows) stack rapidly (IMHO). Though with them it is at 31" and so works like a draw stop for me right where it sould be. The Dream Catcher is a slightly reshaped Hunter with different riser woods.
Sacking may not be a problem, but I find finger pinch really changes my shooting. I can draw a Browning Wasp (56") and they spit an arrow, but my release suffers as do the outside edges of the nail-beds of my index and ring fingers.
