Brinstar honestly just let's ness create a lot of traps with his PK fire. So you can set someone up for a PK fire extended the hit box. PK fire to F Air is about 30 % ish . Adding the extended hit box of pk fire - grab - pummel - Backthrow may or may not put someone in the 30 % + . Now people can SDI out and what not but it's probably still possible.
