The crime is only if we indicate that is the only path when a new
recordist wants to stay within a small budget. Good recordings can be
made with a $200 budget but is close to impossible without seeing some
options from people that have trashed a lot and to be aware of what
there limitations will be with any first setup.

Marty's comments on our knowledge of physics was also negatively taken
by me. All of my filter designs run a smooth cover. Either xtra large
womens knee high nylons, fake fur, knit hats, or womens see-through
swimsuit material made mostly of spandex. Sometimes more than one of
these materials.
You would not have the noise of the corragation if you run a cover and
for a possitive you eliminate the resonance bumps.

I would put the filter up against a rycote zep for durability. And
when they both fail all lumber yards stock the item and you can not
say that for rycote.

I didn't think my support structures were as large as rycotes? I will
look again. Now I am not sure we are talking about the same filter
elements. Want it longer then silicone two together.

Bigger is better. Another reason why it is better than rycote. I
would like a larger one yet. You just need a bigger bin. I use
plastic storage tubs. Doing a lot of laptop multi-channel and large
parabolic recording I do not travel light either.

I think so.

Agreed I always enjoy seeing home made stuff.
For me trying to do some good multi-channel recording costs are
quickly multiplied for me. With my very limited budget I need to spend
what I have on just getting to the field. I just found a 30 year old
RV with 75,000 original miles for $1,500 and can not even pop for
that. I would love to turn an rv into a natural sound recording studio.
