Hi Jason - Yes i still use the 77mm Hutech filter on the 300m lens for RGB shots. I've tried both the Hutech and Astronomik Clip in filters but they didn't work well for me. Hutech model showed a severe light cone on my subs which was impossible to remove with flats and processing...

...may have been specific to my setup as I use 2 Canon f4L lenses with the rear element close to the glass of the clip in filter
The Astronomik CLS CCD filter didn't have the light cone artifact, but I found the colour correction a bit harsher than the Hutech's to my eyes.
So, I bit the bullet and paid the extra for the large 77mm baby which I use on all my lenses with step filter ring adapters!
If you can avoid that annoying light circle I would go with the Hutech clip in version as I know loads of guys didn't have the problems I experienced.
All the best
Doug
