Effective coverage of California's (unique?) sentencing and correction realities

The Los Angeles Times has recently published two notable lengthy article discussing some of California's most notable sentencing and corrections policies.  Here are links along with the headlines and subheadings of these pieces:

• "After 17 years, three-strikes law is still hotly debated; Supporters of the tough sentencing rules say the law applies to a lifetime of crime, while opponents say tough punishments often are out of proportion to the underlying crimes."

• "Indefinite solitary confinement persists in California prisons; Long abandoned by many states, the practice is a last resort for California authorities struggling to thwart gang activity and extract information from the most hardened members. Critics say it amounts to torture."

These pieces have me thinking and wondering whether folks interested in a more progressive and humane modern criminal justice in California and nationwide ought to be more committed to and invested in three-strikes sentencing reform or solitary-confinement corrections reform.  

Do readers California or elsewhere have strong opinions as to which "problem" is more deserving of advocacy attention and/or more politically viable for real and lasting legal reforms?
