Louise, you really must try a few types, they are all so very different.
I have wee Louet 2-row mini combs, and love them to bits. You can't comb much fibre at a time, but they weigh nothing, are balanced perfectly for my hands so I can use them for hours without getting tired. And I can spin directly from them too. But some people really don't like them, find them not robust enough.
Next up in size is the Majacraft. These can be used in the hand or with one clamped to a table, and are not too heavy but much more robust than the Louets. But I don't like them, I find them unbalanced in my hands so I am having to work just to hold them flat.
Next is the Valkyrie range. There are three called 'mini' combs but which are much much bigger than the Majacrafts. 'Fine' are for coarser fibres; 'Extra Fine' for anything that isn't extremely coarse and isn't incredibly fine and 'Superfine' for the very very finest fibres - bunny, merino, cormo, etc. Each can have one row or two rows of tines, I think. You can use them in the hand, and in my hands they feel beautifully balanced so that is less work than using the much smaller Majacrafts, but I would need to clamp one to the table to use them for any length of time. Then they have 'Viking' combs, which are bigger again, nearly the size of full English combs.
I am not sure which of the Valkyries you would want for alpaca - Ravelry user Trencherwork wrote a comprehensive review of all the Valkyrie combs for a wide range of fibres,
hereValkyrie combs are imported, the importer is Donna, aka WidowTwankey on Ravelry.
I haven't seen FW's Forsyths, but I think they are probably similar size to the Valkyrie Vikings, or maybe a little bigger
Finally there are the full-size English Wool Combs. Tremendous capability, make the most delicious slivers, but are big beasts and take rather a lot of arm-power to use. I can't manage them at the mo, with a gammy shoulder. The original make was Peter Teal, you can sometimes get these 2nd hand, or Winghams make new ones to Peter Teal's original design.
If you look at
Winghams' Wool Combs page, you will see that they also make some 'mini combs', which can be used in the hand or clamped, and some 'hand combs'. I haven't seen or used either of these. Reading the dimensions, I'd say the hand combs are similar in overall size to the Louets but have much thicker tines, so would not be as good for other than fairly coarse fibres. Confusingly they describe them as Viking combs, which name is used for the largest of the Valkyries!
