Meade/Discovery Optics - Help with straps/rings

I just purchased a used 6" Starfinder on a pier EQ mount. The purchase was made primarily for the mount. I already have a 6" Discovery dob that was purchased about 5 years ago. Not sure of the age of the Meade Starfinder, but I am sure it is at least 5 years old. Any idea which scope has the better optics? The Discovery seems to be overall better made, FAR BETTER focuser, etc. However, I've heard that the Meade mirrors are fine.

Also, the mount has straps rather than rings. The tube tends to want to slide in the felt-lined straps. (I haven't tried the Discovery in the mount yet, but that is my leaning.) Recommendations on how to stop the sliding? If I make a switch to ring and a dovetail plate, what will I need to do to change the curved mount that is already fitted for a tube? I need to try to find 1. the cheapest solution, and 2. a simple solution.

Thanks!

Hi, I'm not sure what sort of straps you have, but I had an older Edmund 6" f/8 once that used some very flexible straps. I picked up some straps of steel, approximately 1/8" thick , at the hardware store and fashioned some rings. Worked better and was definitely cheap.
