Yep, BIG 10-4 on that
The best and cheapest in my opinion are the Curtis Youngblood Radix cosmetically flawed blades
Here's the paradox: CHEAP blades won't really help you learn auto's, since by definition, they're...cheap.
Many pilots learning autos bounce the landing the first few times, and this can induce a boom strike.. in that case, bye bye boom and (at least) one blade
If you're decent on the sim, get the Radix cosmo's, choose a flat grassy field (no bumps!) and a day with a slight breeze
Once you get it, you'll leave the field grinning ear to ear
