I prefer dips. in my garden as they seem to open in our very wet weather with cold nights better than tets and I just seem to find them more suited to the "English style" garden which goes for natural, simple shapes. I like tets but find the dips more 'graceful' somehow.
I am always surprised though when people comment on having to support scapes on dips. as we never have to do that here and we live in a very high exposed area with very strong winds. I also know of a grower on Bodmin Moor in Cornwall which is very bleak and exposed who also grows dips. and doesn't support her scapes, maybe it is specific varieties but there again we don't get tornadoes here so maybe your winds are stronger.
