I've recommended plenty to my friend, in which he went out and bought, but the catch is I didn't actually have it. I do the research and my friend goes out and buys it first, lol.
Some of the gear I've recommended are a ULA Circuit and Catalyst, Snow Peak LiteMax, Kahtoola MICROspikes, TarpTent Rainbow, Zpacks Hexamid, and some others. I bought a Circuit after him, and has been my favorite piece of gear, but I just bought a HMG Windrider to try out and see if the grass is greener. I got to try out his MICROspikes recently on a frozen lake, and it's another piece of gear I'll buy myself.
