The Lindsay template system is repeatable and reliable, and not complicated at all.
The GRS looks impressive, because it has all these adjustments. But without hands-on training, the fixture will sit on your shelf of "what I thought I needed".
Then you will go out and buy the Lindsay. (and yes, their website sucks bad, and is very difficult to locate what you want) But the product is super easy to use, and you get reliable cutting tools in minutes. Believe me, in the beginning, you spend most of your time breaking points and sharpening. The Lindsay is the quickest way to a new point.
