Heating with thermal solar

Any opinions on a glycol system vs. a drain-back for thermal solar? What are the major pros & cons of each? I'm considering one of these two applications because we do get the rare occasional hard freeze. This will be used for heating radiant floors and DHW with boiler back-up in N. California.

If nothing here, anyone know of a good solar hot water forum or message boards?

Thanks
