I have both. The Jigsaw was supposed to be for oil. Drilled it pin over the bridge. I didn't have the recovery I wanted on the backend on heavier volumn patterns. Plus the coverstock had to keep being brought back earlier than anything I've ever owned. Since it was for heavier oil, that was often. After about three months I invested in the 715C after my wife had success with the 715A. I drilled the 715C Rico, and it is WAY better than the Jigsaw. Track is the way to go, and I've been a fan of both Hammer and Track. I'd recommend the RICO drilling also. I've used the 715C on 50 ft patterns, and it still picks up in the middle with a strong controlled recovery on the backend. I have mine at 500 grip dull.
