My main problems with the Pirellis is that firstly they cant be pasted into the ground for the first 5 laps of the stint. I think this is what needs to be worked on. Lap wise they have the degredation right i think.
Second problem is that there is simply too many marbles on the track, a car weighs 5kilos less at the start of a stint to the end of a stint if fuel levels were the same. That is a fact. At the end of a race there is arround 500kilos of rubber at the side of the track. That is based on a 3 stop strategy where a driver has 4 stints.
Bridgestone had only arround 250grammes of weight loss on a set, and thats one that went like Vettel at Abu, one set that did the entire race. However Bridgestone had F1 rubber sorted out.
If i were Pirelli and the FIA id think about a change in the regulations, where 3 compounds are taken to each race, something like this:
RED: Hard: 3 sets - Lasts 22-27 laps at a 5Km lap length
YELLOW: Medium: 4 Sets - Lasts 15-18 laps at a 5Km lap length
GREEN: Soft: 5 Sets - Lasts 9-12 laps at a 5 km track length
WHITE: Intermediates: 5 sets - Lasts generally 35-40 laps at a 5Km track length
BLUE: Wet: 4 Sets - Lasts generally 50 Laps at a 5Km track length
Those tyres are avalable and muts be used throughout the weekend. It will give any car arround 170 laps for the weekend, and 850Km of potential distance to play with. Each compound should have arround 3 to 5 tenths of a lap time intermediate at the start of their life, whitch id place at the first 3 to 5 laps.
However id introduce a FP1 driver rule, where a extra set of softs are avalable for that driver, whitch will give the teams an extra 50Km of distance to play with.
As for Quali; Drivers in Q3 have only one run, on a set of Green/Softs, and must start on that set. Id also make that set unavalable for Pree Practice sessions. Any driver that is put out in Q1 dosnt need to worry about the 2 tyre compound rule, where every driver has to use at least 2 compounds in the race. Q3 would last for only 5 minuites, and the 5 mins lost from Q3 would go into Q2.
In effect it will give the Q3 drivers the headache of going for a 4 or 5 stopper, the Q2 drivers a 3 or 4 stopper and the Q1 drivers would only need 2 stops. Meaning that the race would me a massive strategy fest and also the last few laps would be where the cars came together, and the DRS would come into its own.
However id make a tweak to the DRS rule where each driver was only allowed 20 activations on "DRS Approved Straights" per race, so that DRS was used as a tactical tool you could use for attacking or defending posistions.
It would make Quali much better, the race would be a almost unpredictable, and the "show" or specticle would be such that it would mean that F1 would, in my opinion, be a much better sport.
