What's the best way to get closest to the reaction of the 505C?
I'd like to try one but they seem to be very hard to find.

Which ball would be easiest with drilling and/or surface prep to get a simialr reaction that the 505C would provide: 505A, 505T or 715C?
These seem readily available.

My inclination would be to dull and use a lower pin (larger Val angle) on a 505A
or a milder drilling on a 715C.

Your best guess?
