Some great ideas that prospectors are renowned for, however................
Nothing will change my view until extensive up front parallel testing has been done with original SDC and modified version.
AND! Why should the public, after investing their own money in a publicly untried product be out there doing the road tests for the developer of this extra?
Maybe the end result will be a "win win" for all concerned, hopefully so?
Before I'm jumped on with, "If you don't like it don't buy it" etc.
Once bitten twice shy, the below photo is of a coil I bought back in the SD2100 days, now hanging on my fence with other memorabilia.
This coil was a mongrel, every twig or rock I touched it rang off.
Had more money than sense back then, should have sent it back.
Ended up pulling the cover off revealing the internals were flapping around in a void. Contemplated filling the voids with silastic but turned to Monos and it lay in my shed for years until deciding to cover ugly fence with memorabilia which is now over grown with Jasmine.
