Reply to Is an S2 better than an APC 40 for Traktor?

Decided to learn Traktor and started off using my APC 40 with the collision mapping. Seemed a little confusing at first but once you figure it out, it seems to work fine.

My question is, would buying an s2 or even an s4 give me any more control? Sometimes I can see how having the jog wheels would be nice, but not sue what else.

Currently my setup is an APC40 with a MF Pro. Would an s2 or s4 be an improvement? Also, does anybody else here DJ with Traktor and an APC 40.
