Default Collision Avoidance Systems for gliders

JS,

I've been flying with transponder and TPAS for over 5 years, some of that
buddy flying with transponder equipped gliders.

When close to other transponder equipped gliders, the TPAS essentially goes
deaf. If both gliders are being interrogated by ATC or TCAS at very nearly
the same time, the nearby glider's transponder reply will occur while your
transponder replying as well. Your transponder blanks the TPAS receiver
during this period.

A question for someone with transponder and PCAS experience:
How do the collision avoidance systems respond to transponder
equipped gliders in a gaggle, or transponder equipped tow planes?

I only have experience with 2 installations in gliders:
1. Transponder equipped, no collision avoidance system.
2. FLARM.

Searching for the next installation, hoping it can consume little
power, integrate with power traffic, and behave as well as the FLARM.
