You are supposed to sit "IN" a chair, not on it.................. that's why a lot of bike seats are crap!!
I have mini apes on my Springer and I tend to sit back in the saddle. However, you could keep ya 'beach type bars' and sit back by changing ya risers. That's cheaper than changing bars for sure unless you wanna entirely change the style from 'beach' to 'apes'.
