209 GP-A Soft versus Hard/Med Rear

I've been using the 209 GP-A Med/Hard for trackdays and are getting on average 4 trackdays out of the rear (Although two days at CMP recently have shredded the rear)

...Anyways, I am looking at the deal on the 1 front and 2 soft through Race Tire Services. Wondering how much less days I will get by going with the Soft Rear.
Should I stick to the Med/Hard rear if I want to balance max life and grip?

Thanks

 

what bike are they on? cmp will toast it really quick.

 

It was on a stock 07 GSXR 750. I ran a best of 1:47 in the two days (Intermediate Pace).

 

Stick with the medium/hards. The softs barely last a full day.

 

I ran the 209 at the beguining of the year on my RC, I got bearly 2 days(baby them), if you get the chance get the 211GP-A are much better and less prone to cold tearing. That`s what I have now on the rear of the RC :up:

+1

 

Medium/Hard would be my choice also.
