Hi Fm, welcome!
With your 27.5 draw and using release with your compound, I suspect your draw on a longbow or recurve will be shorter than that, could be anywhere from 26 to 27" depending on if it's longbow or recurve and also how your shooting form develops. Some say the switch is easier with recurve, but that's really a personal thing. Like the others said, too long of bow for archers drawing under 28" may not get the umph out of those longer limbs. Somewhere between 52-60" and 50-55# would probably be a good fit. All depends on how you hunt also. Myself, I like to use rather short bows when hunting out of tree stands and blinds.

If you're going to go all out for a good one and stick with that bow, good luck. Longbows and recurves built by different bowyers all have their own characteristics. Seems as though there's many trad archers that are constantly trading/buying, trying different bows looking for that "perfect" bow. I'm chomping at the bit right now waiting for my Fedora to arrive.

I don't know all that much about longbows, so if I were to recommend some quality bows they would be recurves (in no particular order)....
Bob Lee, Groves, Morrison, Palmer, Fedora, Black Widow, Brackenbury, and Schafer.... One another note - Chek-Mate bows are quality bows, but do not reflect the higher prices of those listed above. Don't let that fool ya, they are good shooters like the rest of them... go figure.

Actually the list goes on and on. Here's a website that lists most traditional sources available today.... thanks to Brandon Byers, a wonderful listing to browse.
