Default Tires/inserts versus weight

Usually, I use molded inserts, but I would like to try out some sponge-types. But I've read that they can have heat-problems at the end of a race.

The temperatures on the tracks I race on, vary from 0 degree celsius to 25 (32-77 deg. F)

During races, I only run for 5 minutes per. session with 30-60 minute pauses inbetween. During practise, I run for around 8 minutes per session, and often only with 10 minutes pauses.

Are sponge inserts proper for these conditions?

In my experience foam inserts can help in very low grip conditions, but don't provide enough support for the tyre when the grip is OK. This leads to fast and un-even tyre wear.

I don't think any weight advantage will be that noticeable.

Sounds reasonably. Thanks.

Generally what you will see with a too soft insert is excessive wear on the inside edge of the Tire (grooving). A large air gap can cause this too.
Unless the Traction is very poor (even with the best tires), I would stick with Molded inserts.
