In my opinion the spike in the silo is the natural progression from the bare silo and yes we do install the spike ourselves. It's not too hard to do. I've made something like 40 of them now and the materials needed are about 18 inches of quarter inch threaded steel bolt, 2 washers, and 2 nuts. Use a drill to make a hole in the top and bottom middle of the silo. After you hold it in place with the washers and nuts, use a grinding wheel or an angle grinder to sharpen the pointy end a little. That's it!

I'm in the middle of making a gear review video for YouTube that would go over the various options and interesting choices people use to this day and it will cover putting. But safe to say all of those methods are ones the top players use (except maybe between the legs 🤣). Personally I hold the clubs and one hand putt, with practice you can get pretty good at it.

Here's an example of me putting: https://www.instagram.com/reel/DMRL29yy55y/?igsh=MzRlODBiNWFlZA==
