Unlike you I've only played a Pick 5 once in my life and hit 4 out of 5. Rarely play Pick 4's either, but when I do it would only be if there was a vulnerable heavy favorite in the 1st and to consolidate the ticket I would leave him off. The reason being is if he wins everybody is still alive so it's essentially a Pick 3. Used to play alot of Pick 3's at Meadowlands a long time ago and hit some good ones, using the same strategy in the 1st leg if there's a heavy favorite who looks vulnerable. The tickets were $1 minimum and I tended to go 4 by 4 by 4 for a cost of $64. Had a 10 percenter who used to hang around and knew where to find him if I needed his services. Didn't like the guy but he served a purpose. Turns out he was a former cop from New York.
I knew you had to gamble a little bit
Great story

With harness I usually only play exactas tris and supers..no Pick 5's
The pools are to small, especially with my betting range.
T- breds its almost all horizontals.. I do use my singles on top for vertical though
