Left foot control problem

[JJKK]

I can do 8ths at 140 to 150 clean with my left foot. Obviously this is a problem when trying to get faster double bass. Are there any control exercises I could do besides playing songs and grooves with my left?

Maybe some quickness response work (fast twitch work), like playing double strokes instead of singles starting at a slower tempo?
I'll play Can't Get Enough of Your Love by Bad Company but doing doubles every down and back beat (correct terms?). Instead of the normal boombasnap of a kick and snare, I play baboom baboom with the snap snare on the last kick boom. You'll really hear if you're off when at the snare backbeat. It's a b...., but it helps me overall.
Then some stamina singles work, doing twice as many consecutive lefts as right strokes.

long shot here; works moreso for HH left - might work (dunno) for double bass
and I'm feeling generous.
