countermarche vs. counterbalance?
I've been reading a lot in books and online about what a countermarche system does (which is what I'm used to) and what a counterbalance system does (which I've only used briefly on a 4-shaft loom). What I haven't been able to find is a good explanation of the difference(s) between using an 8-shaft countermarche and counterbalance system.
If anyone here feels like taking a stab at a simple comparison I'd be grateful - I'm buying a Berga Savonia counterbalance loom (see my other post about this) and was planning to convert it to countermarche, somehow - but I'm wondering just how much of a difference it will make, and in what weaving arenas? I get the impression that weaving unbalanced weaves is harder with a counterbalance system, but is it that much harder, or does it just require a different tie-up/treadling technique?
What's your experience, please?
