WTD: Small, slack full suss frame

I’m idly on the look out for my sons next frame. Reasonably flexible, but I’m thinking

• 27.5
• size S
• 130-150mm ISH travel
• straight uninterrupted seat tube to allow good dropper insertion
• slackish – <66 ISH HA
• threaded bb would be nice
• tapered steerer
• non boostb would be handy
• Sick AF, obvs

I’m thinking something like Transition Patrol, Alu SC, Trek Remedy, Canyon Strive, Airdrop, Jeffsy 27, that sort of thing. No Commençal/Orange/Cannondale.
Ta!
