Planning on switching from KID to Slav... thoughts?

I've been wrongly playing the KID because I disovered I was better positionally; plus, I play the caro-kann so the slav should be a good choice for me. How should I go about this change?

Hm...is the Slav positional?  Seems pretty wildly tactical to me.

BTW I don't think the CKD has all that much to do with the Slav Defense other than starting out with an early ...c6. Next time try telling us what variation(s) of the CKD you play and what variation(s) of the Slav you're planning on using and maybe you'll get more specific recommendations and suggestions  GOOD LUCK!

Said every player under 2500 ever

The Slav is an excellent match to go with the CK 

1. In both you often get in similar pawn structures.

2. You can handle transpositions such as responding to 1. c4

I've tried to give it up myself before, but I end up doing even worse with other stuff. 

I was going to take offense... Then I realised you're right.
