I've been very impressed with mine in 225 profile all round too. Mine sit on 8j wheels though. Wonder what 235 would be like on 8j, just on the fronts, anyone running that setup? Got to be careful not to create too much drag obviously.
Mine does tend to spin up quiet easily if I'm too harsh with a 1st to 2nd change so I often wonder how some say they get more traction. I normally have to do 1st gear part throttle up to just under vtec, change to 2nd and then plant it for a quicker launch, especially if it's damp. I'm all stock too other than a lightened fly.
Only tyre I'm tempted to try is the AD08 but as people have already said, to see any improvement over the F1's it probably needs to be on a track. For road use the F1 is likely the better choice, particularly in the wet.
