snakes,
Moreso ..... on a line from pap to pin that finishes above the ring finger hole.

Yes,......whatever is favorite drill is,.....have 2 balls with that, (label), then have one stacked, 4x4, then have a arcing drill, or earlier roll drill, say 4x2.  Start off with 3 inch pins at least.  He could also get a 3-4 inch pin out ball and do a 2.5x5 as long as the pin and pap make a line that goes above the ring finger......

Ragnar has done experiments with these type drillings (he's a high tracker too) and he may chime in as well
