Re: solar filters

Personally I have a Coronado 40mm filter set, a Daystar Quark, a mess of Orion glass filters and a roll of Baader visual film.
The Coronado gives the best solar views, followed by the Quark, followed by the glass filters and the film in last place.
I have tried a wedge but do not own one.  It seemed about on-par with the glass filters to me.

I'd suggest as a (cheaper) still-quite-good alternative:

Two versions: one for visual, one for photography...

The wedges are a bit better, but... be aware of the potential problem of backfocus with the wedges... check your system's focus distances before buying... ;-)

Don't go for glass filters...

A Herschel Wedge! Baader or Lunt. I've used them on my AP scopes with great success.  The solar load on a quality refractor is no problem so long as the scope has front lens elements only.  You'll get unbelievable views with your 160 and a wedge. Make sure to get a 2" model and to use additional ND filters for visual. The Baader comes as a kit with everything you need. 

Of course you can only use a wedge with a refractor!

Curious as to what solar filters folks have found to be good...I was thinking of a Thousand Oaks glass filter for the 160 EDF...anyone have one for use with this scope...what size fits properly...?

Vega, the brightest one, is now dropping towards the west.  Can it be half
