Meds vs hards

So, mediums still unusable now?

They are usable it's a matter of finding the right wear and temp. 

Usable but generally pointless when you can select soft for the majority of races. We changed our league to a two tyre dry race compound and it has created more interesting races.. its a shame we have to create our own rules to do this. I use mediums sometimes to comply with this rule and they do ok....about 0.6 off soft pace on average 

We race at 50% length.
Id say mediums (given your choice medium/hard)
The updates have basically made hards absolete in 50% races.
Tho if your choice would be bigger id say softs.

Soft, Medium & Hard in 100% are equally matched in terms of wear but the drop-off in the tyres seems to be at fault, you have to go over 60% usage of Soft before Medium has a chance and use over 50% Medium for Hard to have a chance. 
 

Making own rules and forcing to use SS & S or SS & M or SS & H at a race would work, but it also works fine if you do away with all the other tyres and everyone uses just Soft's. :D 

At least to me, they don't seem to be useful in any situation
