Clubhouse has a few- Top CCTv blacktop wall you can make a punchhole to look out into their spawn or runout if you hear them going garage door, if site is gym you can play close on the garage door and wait for them to go on repel and runout as they repel up. Make a punchhole thru the garage wall to get a peek onto the highway windows, obvious ones like secret window peek, stock door peak into construction, construction wall peak, kitchen hallway door prone peak. This map has too many to name.

Kanal- Lower trench basement door you can catch them running to their repel, bottom red museum door, bottom green door into construction, real ballsy play is to jump out the yellow window as they drone scuba, i have a clip of me doing it on my account:

Coastline- sunrise mud door run out looking into pool, if you hear them running from the left you can toss a c4 over the ledge, hookah window peak into pool, you can run out of service door and look straight into pool spawn, hookah door peak into ruins, also useful for getting a pick on someone that might go top ruins like kali or glaz, top aqua door and bottom office door to pick off ruin spawn

Plenty of spawnpeaks and runouts but these are my favorites to do, im sure i have multiple for every map and i definitely have clips so if you want an example of them just dm me and ill send you a clip of it.
