A simple system:
- Edelrid powerstatic 11mm dry lifeline (hi vis orange - I always advocate an 11mm true kernmantel, to EN1891 type A for knotted strength an sufficient energy absorption). Anchored with 2 trunk wraps, split tail, and two lcokers (for continuous knotted loop emergency descent).
- Petzl Ascension - left hand (doesn't clash with Croll), clipped through top holes (important to retain rope and prevent cam slippage) with Oval locker to a,
- Petzl spelegyca - attached to Oval /HMS krab (built in enrgy absorption) that holds the,
- Petzl Croll - attached to harness with a,
- Petzl Torse - Bi-colour to easily avoid twists when donning over shoulder. Lots of adjustment for increased length and easy on the move adjustments. Quick release enables entire system to be released at the back.
- Adjustable footloop (change of length required for RAD system) to quicklink on Ascension for left foot.
- Petzl Pantin to right foot.
- Small clip to retain rope to right leg (prevent rope pulling out of croll).
- Petzl Grigri for descent (attached to krab with thin cord so as not to drop during changeover - can be left attached to sliding D, ready to go).
- Petzl strings to lock krabs in alignment.
No, I don't have any deal with Petzl. But they really have got a compatable Frog Walker system sorted!
Micro pulley used with some of above for a RADs system. Edelrid Eddy a better option than Grigri for treework (can free ride, be used one handed and auto locks).
Harness is a TreeFlex - unrestrictive design, low fixed clip point for Croll, Sliding Dee to changeover to DdRT/Descent/more efficient work positioning.
2ft/second ascent rate, against stem, covered in Ivy, excellent bio-mechanical efficiency and ease (well, climber was a bit stiff in the mid section due to a Lat injury).
I can almsot run with this system now. Doesn't matter where the line is set, as long as there is standing room - air, trunk, ivy, open, closed.
Entire system can be removed by just two clips, leaving on rope to be retrieved later (tie a knot above to prevent them moving up the line).
Important system safety factors explained here:

Do not attempt this without adequate training/supervision first.
Think ABCD before lift off:
Anchor - is the line set securely to a strong branch?
Belay - is it set and secured?
Connections - are they all clipped in securely?
Descent - Do you have the means to return yourself to the ground?
Hope its found fun as much as useful.
