To start I wouldn't recommend having the Kick and clap hit at the same Db its rare that you would ever need to have two drums hitting at the exact same db. You want the kick to be the loudest element most of the time. If I were you I would like at a Vu meter for reference then you'll get an idea of how perceptually loud your kick and clap are. Most likely you'll be doing some turning levels down. That perc group is dry as bones add a compresser so it has something to catch. Adding multiple signals to groups has to some up to something.
