Baseplates and Mag Extensions that fit with the Platypus

What are some baseplates and mag extensions y'all used that fit or did not fit with the Platypus? Mainly with the mag funnel. Been kinda window shopping around to see what worked while I been saving up to order my own Platypus. Been leaning on either the Taylor Freelance +5 baseplates or the Tyrant Designs +5 Mag Extensions.

Pic of the Platypus setup I plan to get.
