You need to stay off the grass 012SS's are great tyres for me and have none of this all or nothing feel you mention.
Run em low pressure for road and track,
32R 30F.
As you only have 200 mile on em they will only just be scrubbed in and you may still be feeling the release agent from the mould being scrubbed off causing you to think they are twitchy.
You know they are good tyres as are 99% of the others available on the market today but personal preference will always prevail.
One thing to mention is that they are excellent in the wet for road or track.
On my third set this year and will be looking to replace with similar or the new Bridgestone thats rumoured to be coming out/already out?

Let me know how much you want for the tyres if you decide to sell?

If you want mileage then the BT010 are v good road tyres and were decent on track as well with a better life span than the softer 012SS's
My opinions only and we all have our favourite tyres.
