Reuse the stock rubber elbow connector and use a 5/8" barbed hose coupler to connect a 5/8" hose to it. A quality automotive hose should never collapse. The Prodigy turbo kit uses very sturdy cotton wrapped/reinforced rubber hoses made by Goodyear.

For a boosted system, it's most important to put a catch can on the make-up air side of the system (hose that runs from driver side of engine to air intake), because this is where you'll get oil vapors coming out of the engine and into the air intake, coating the compressor and intercooler, reducing effective octane of the fuel while at high engine loads and boost where you really don't want any knocking to occur.

On the PCV valve side of the system (hose that runs from passenger side of engine to intake manifold), oil vapors only flow into the intake manifold when there is vacuum in the manifold (lower engine load, part throttle, on a boosted engine). It is less critical to remove oil vapors under these conditions.

Of course, the ultimate setup is dual catch cans. One on each side of the PCV system.
