I usually shoot wood with trad gear but I think carbon is probably going to be the best bet for my Africa hunt. I am going to be shooting 190gr BH's with 100gr steel adaptors and 100gr brass inserts. It will also have the 20gr. outsert/footing. I want to use the GT trad blems from Big Jim's but I'm not sure what spine to go with having it front loaded like that. They will be shot from a 63# brachenbury shadow recurve, that I believe is center cut but not past. It can only use B50 strings. Arrows can be as short as 28.5" back of point if need be. Will have 3 4" feathers and nock collar. What is the general opinion on the most likely spine that will best work? I know trimming and tuning will be involved and I'm assuming the .300 spine is what I will be looking at, but before I spend the money I thought I'd ask people with more knowledge on it than me.
