Goat,
HH Freeze (that used to be known as ProWool & HH Warm) is a very good baselayer in many ways but due to the high wool content it isn't very fast drying.
There are several factors at play in how fast a baselayer will dry:
fibre properties
weave
weight of fabric (per square metre for example)
fabric treatments (and their condition with age)
and also cleanliness of the fabric but this is less of an issue after passing through the washing machine.
I am a little surprised that Dave finds dryflow from LA faster drying than HH. I assume he is talking about HH LIFA (HH Dry) - 100 % polypropylene. If he's talking about HH Warm / Freeze / Prowool or LIFA Versa / Cool I don't find this surprising, however.
The reason I say this is that the fibre properties of polypropylene are such that, all other things being equal, I find it to be the fastest to dry of any baselayer fabric I have tried. Polypro is the least hydrophilic of all the baselayer fabrics, meaning that it holds the lowest percentage of water by weight of fabric. In fact, a decent spin cycle will get LIFA Dry (previously known as LIFA Sport) almost completely dry.
Dave's LA Dryflo might have dried faster if the fabric itself was lighter weight. The thinner the layer, the quicker the water will evaporate. Plus LA use a pretty good fabric coating making their polyester one of the better ones for wicking moisture. A thinly spread layer of moisture will dry faster than the same quantity in a few droplets. I don't own any dryflo stuff so I can say I have tested it.
Purely from my experience, the speed to dry table goes something like this (fastest to slowest)
HH LIFA (Sport / Dry)
SubZero CoolT (Tactel Aquator nylon)
SubZero Factor 1 (Tactel nylon)
HH LIFA Versa (now known as HH Cool) - polypro/polyester hybrid
Patagonia Capilene
Decathlon / Kalenji / Quechua baselayer (polyester)
HH Hybrid (mixture of HH Prowool & HH LIFA Sport)
HH Prowool/Freeze/Warm (polypro & merino in various percentages depending on which model)
pure Merino
P.S. I think HH have been very foolish to have changed the names of their fabrics recently as it is confusing for those that haven't kept a close eye on what they've been up to!
