You can't do much wrong with that front. Best one IMO. 32-33 HOT....set it and forget it. You sure that rear # isn't the date code? For Most Ntec rears, 21 Hot off warmers and I aim for 23 Hot off the track.
I haven't seen the UK stuff say "medium" as they all have 4 letter compound codes. Even the Moto2 tires I had were the same. However, the GP-A's (US) do say "soft" or "medium". For the D211GP Ntec (slick or DOT) or the D211GP-A, the pressures I said above work well.
The front says Ntec the rear is a gpa so that settles it I thought they were both uk tires , either way great tires mite just stick with them
For what it's worth, I swear by the these tyres and use them on the road and track here in Australia. The GP-A's are used in the ASBK championship and have had problems with severe blistering after 20+ laps in warm temperature but I only ever use the Euro made tyres. I use the same pressures as Goodmatt78. I source my NTEC's direct from the UK (although I'm pretty sure they're made in France now).
That front kicks ass show minimal wear and saved my ass a few times going in to hot threw it over and It stuck like glue . Think im a dunlop guy
