Welcome! You sound like you're on the right path.
Based on the type of bow you described some great bow choices for you would be a Javaman Elkheart (he can build the grip without a thumbrest) OR Shrew Classic Hunter, a Big Jim Thunderchild, a Toelke Whip HS, Stewart Slammer Special or Lil Slammer, a Cari-bow Wolverine, or a Centaur with a low wrist grip to your specs. Those bows would put a grin on your face and the craftsmanship is impeccable. The TG classifieds are a great resource for used versions of the above named bows and you can also find them other places on the net. Order them new an you will be treated right by the bowyers as well. I just named a few of my top picks. There are so many great choices out there, as the other guys have already named a few. Consider Sarrels for sure, you're lucky to be near them and could even discuss a bow build in person! Have fun!
