31mm f1.8 vs. 35mm f2.8 macro (autofocus question)

I just ordered a Pentax KP and currently already own a Pentax 35mm Macro with my K01.  The autofocus is painfully slow with the K01.

The thing is, I don't want to use this lens for macro only.  Will the autofocus be significantly better when paired with the KP, or am I better off buying the 31mm.  I don't know much about the 31mm except that it is very good and very expensive.

I am EXTREMELY impressed with the sharpness of my 35mm Macro. I normally use Fujifilm cameras and lenses and I don't think any of my Fuji primes are quite that sharp except maybe the 14mm which I never use and plan to sell.

So does the 31mm focus that much faster than the 35 macro on a more modern Pentax?  Thanks.
