Is there a max spring weight limit on a GF Mk3 base depending on extension and/or grip?

[Falconeer]

There has been some discussion regarding this but I'm hoping to ask new, but associated questions.

1. Are 50/50# springs generally accepted use if paired with a 100mm extension?
2. Same as above, but with the 200mm extension?
3. Does the grip used affect spring weight allowances?
4. Are there any limits to differing total weights per axis?

Thank you in advance for your time!

Max spring combination per cam recommended is 2x50 for MKI and MKII base and 1x50A + 1x40A for MKIII base. Grip or extension doesn't matter.
And here are some values for the new springs.

Fantastic! Thanks!
